You feel uncomfortable about Scepter 4 year-end track, is it because you're Reisaru shipper and in that track Fushimi ditched Munakata to chase Misaki? You know that the track was made by Yellow, one of official GoRa's members, right? The track is, sadly for you, canon.
Fushimi ditched Munakata? Oho, I support it fully. Like hell, sometimes on Drama CDs or short stories (especially Gakuen K) Fushimi is so tolerant with Munakata's shenanigans and made me want to scream "just kick him and run away Fushimi!" (Case point : Munakata fishing trip, Munakata got handcuffed, Munakata's King Game, Fushimi became Santa Claus). And for me, the fact that Fushimi can refuse Munakata and willing to do so without any fear or hesitation is the cute and healthy point of Reisaru. He already coldly rejected Munakata many times you know, like when he refused to accompany Munakata on his hobby because it reminded him of the time when he was roped by Totsuka into various activities, he refused to play cheese with Munakata, he refused to see autumn falling leaves together with Munakata on their day off, etc. So yeah, the fact that Fushimi ditched Munakata to chase Misaki didn't bother me at all.
So what made me feel uncomfortable for this track? Just one word, Timeline. The explanation is a bit meta-y so if you don't want read my rambling, the short answer is there's discrepancy with the main canon timeline, and while it's not impossible, the implication made me uncomfortable. Again, not impossible but hella uncomfortable for me. For full explanation....
See, for me, since most of K Drama CDs are mostly gag tracks, the ones that I treat as canon are Drama CDs that I think can be slotted in canon timeline. Drama CDs like Crow's Repayment, Snow White, and Izumo's Room are definitely not canon because there's no way those were happened on main timeline situation. Drama CDs like Everything Sank Except Me and That Guy and Munakata Fish The World is obviously placed after ROK (since Munakata got weakened like he can't pull a tire and Sarumi's improved relationship). Other drama like Munakata-kun's Strap, Elevator, or For Justice can easily be slotted in pre-anime or even post season 1. Window Shopping, Figure Direction, and Private Hero are obviously pre-anime by the casual appearance or mention of Mikoto and Totsuka. There are Drama CD that used as blatant promotion of K Project, like Guys Meeting in The Shower and it's Girl Version counterpart which completely break the fourth-wall by "Hey we are bunch of K boys in K world let's we dip in hot water and talk" which is definitely not gonna happen in canon.
So what category is YEP (Year End Party) Drama CD? It's logical enough to happen on canon. It didn't break any fourth wall. If we assumed that YEP Drama CD is truly happened on canon, on what period it's happened? It's definitely on pre-ROK, and by the casual mention of Mikoto, can it happen on pre-Season 1?
The answer is no. Why? Because unlike other Drama CD who has no mention of time as our foothold, YEP Drama CD has two hints about the specific time it happened. First, it's about year-end party, so the drama CD was happened on the end of December. Second, by the mention of ABCDEFGH as a squad that was expected to come by Munakata, it means that Scepter 4 Special Ops Squad was already formed, since before it ABCD were leaders of 1st-4th platoons and EFGH were ordinary swordsmen of 4th platoon. Is it impossible for them to have casual gathering together? No. Is it impossible for them to get grouped together on formal gathering with their boss? Yes. Because based on Scepter 4 structure, they were not a group yet, they were not even on the same platoon. Like, if EFGH was invited, how about the rest of 1st-3rd platoons? How about the 5th platoon leader and members? (Poor 5th platoon, they didn't get any screen time except a brief mention on Season 1 episode 8). And before Special Squad was formed, Fushimi is just an ordinary rank on Intelligent Division, so why did he come to gathering for Scepter 4 bosses and leaders of Swordsmen platoons, with bunch of troublemakers from 4th platoon? (I mean, yeah he is Munakata's favorite and the King's private soldier, but that was not.... an official title). The Drama CD with the mentioned casts was not logical to happen if Fushimi and ABCDEFGH was not yet grouped under a special group, which is currently named Special Ops Squad.
Now when we established that YEP drama CD happened on late December, before ROK and after Special Ops squad was formed, let's look at the detailed timeline of K :
Special Ops squad was formed on Side Blue, detailed time was on 1st May 2012. Fushimi particularly joined Special Ops Squad and became the third-in-command on 6th June 2012. So the mentioned casts (Special Ops Squad) plus Awashima and Fushimi were expected to have Year End Party together with Munakata, it certainly happened on late December 2012. And what happened on December 2012? Apocalypse well quite almost close to that. On 7th December 2012 Totsuka was dead, and 12 days after, on 19th December 2012 Mikoto was dead, killed by (a very unwilling) Munakata. So if YEP drama CD happened on 23-31 December 2012, more or less a week after the end of Season 1 and Mikoto's death, then...
-Scepter 4 ditched Munakata even thought they were aware that more or less a week before their King killed his friend. If the rest of squad didn't know about Mikorei's relationship, then at least Awashima knew how hard mental blow that was received by Munakata on K Season 1. Yet she still ditched Munakata. I don't know what happened on previous YEP, but would the ever loyal Awashima ditched her King when she knew that Munakata was very possibly on his sad and hurtful period?
-Fushimi taunted Yata with mentioning Mikoto just more or less a week after Mikoto's death. Sure we knew that Fushimi could taunt Yata even after Mikoto's death, but (I hope) he didn't specifically search for Yata and taunt him with how Homra and Mikoto is suck just after Mikoto's death. On canon, after Mikoto's death Fushimi avoided the hell of Yata and Homra, on Missing King Yata called him first, and on ROK, their meeting was coincidental.
-I love Scepter 4 as a whole, and I particularly love Munakata and Fushimi on the same degree. But my love for each of them is a little different. I love both of them to be happy of course, but if Fushimi got flooded with angst, I will feel "oh yeah Fushimi angst, mmm delicious, give me more" but if I stumbled upon Munakata angst I will feel "noooo don't be sad, I don't want him to be sad, please someone fix it!" Yeah sorry Fushimi XD. And that is the reason why I can't enjoy Mikorei after Mikoto's death, because watching Munakata's constant brooding over Mikoto's death is damn uncomfortable for me and I can't even feel sad along with him for Mikoto's death (I don't hate Mikoto, but I am indifferent about him). So yeah, hearing how Munakata sounded genuinely upset when Scepter 4 members ditched him, when Fushimi ditched him, when I heard Munakata's lament that he was alone on the end of video, when more or less a week before he killed his friend, I can't enjoy it. I can't laugh for Munakata's misery, I feel uncomfortable as hell instead.
Please note, just I said, the track is not impossible to be canon. Is it possible for Awashima and the rest of Scepter 4 members to be annoyed enough by Munakata to ditch him even though not long ago Munakata killed his friend and almost died in the process? Yes. Is it possible for Fushimi to taunt Yata with Mikoto after Mikoto’s death? Yes. Is it possible for Munakata to be left alone in a bar? Yes. BUT, as Fushimi, Munakata, Awashima, and overall Scepter 4 fans, that kind of portrayal makes me uncomfortable so much, especially since I valued Scepter 4′s bond so much and don’t care (or you can say quite disliked) about Sarumi’s taunting and fighting, also Munakata angsting over Mikoto. Also if the lack of Yata’s anger and depressed over Mikoto’s death means that the Drama CD happened before Season 1 a.k.a December 2011 (Fushimi joined Scepter 4 on October 2010, so December 2010 would be his first YEP and he shouldn’t know about previous party), then as Scepter 4 nerds I need explanation why only ABCDEFGH, Fushimi, and Awashima that was expected to come when they were not on the same squad before and Fushimi even just an ordinary member of Intelligence Division that rarely associate with Swordsmen Squad as Hidaka pointed out. Compare that to another Scepter 4 annual event like Flower Gazing that included Zenjou, Yayoi, and even we can assumed that there are other Scepter 4 member joined on flower gazing on other places. Also, Flower Gazing as annual event is already mentioned 4 times but there's no mention of Scepter 4 year-end party except on that Drama CD.
Speaking about portrayal, I also don’t like some of jokes on that track. Namely when Munakata said that he installed surveillance camera on Scepter 4 dorm, Awashima’s dorm to be exact. I knew that Munakata is an S and can quite ignore the concept of privacy and personal space, but as a boss and a man, just like Fushimi said, that action is a crime. And not the funny one. Awashima should and must protest for that, no matter how loyal she is to Munakata. And Fushimi as the main advocate of privacy and personal space should not accept that kind of behavior from Munakata and didn’t let Munakata be with just a simple protest. Honestly, if I have a boss who pulled that stint of me, no matter how amazing he is, I will lose my respect on him. And I respect the hell outta Munakata. I will not say that the track is mischarasterized Munakata, since as you said Kabei Yukako (Yellow) is the writer and she wrote an amazing Munakata in LSW and Sand Castle story, but maybe she played with fandom jokes “tyrant Munakata” a little bit too hard. So yeah, I prefer if that track, especially that particular aspect, is not canon.
Not that I hate the whole track of course. I like some trivia about Scepter 4, especially the ones that was confirmed canon on other materials like Awashima loves plushies and Benzai has younger sister. I also like when Fushimi can baffle Munakata with his card trick. But still, Scepter 4 YEP Drama CD is uncomfortable for me.
Also track like Megane of Blue is also written by Gora Orange, it didn’t break the fourth wall or seemed happened on alternate universe, but you don’t actually believe that in canon Munakata truly became crazy if he lost his glasses right? Especially since we already got 2 glasses-less Munakata and he turned out just fine (three if you count Optician Drama CD, which is canon since it was mentioned on Countdown). On drama CD, script writers often exaggerate characters to create a joke, either Gora or non Gora.
