Not a request, just a comment: in your friend with benefits post with Sylvain you had a part that mentioned “possible angst? Felix’s secret crush messing around with his best friend” and GOD that would be so such a good idea for a fic or even just a headcanon post. I love everything you write in general though! Please keep it up! 😄
👀👀👀 Ahaha, lucky for anon, I didn't have time to finish any of my actual asks because of school and babysitting haha
but I did get to quickly give this hc list before being pulled away~ (++I totally adore angsty scenarios like this-)
Based on this post: Sylvain Friends With Benefits HC's (But he's falling in love with you-)
Felix knew something was up rather quickly. He'd always been keen on shifts in a persons character, and it was very apparent in your sparring when you put more weight on one foot than the other.
When he questioned you on it, you simply said you were trying to accustom yourself to different conditions when fighting. Who knows, you might injure one ankle on the battlefield and have to fight with only one good foot!
It was clear you didn't want to reveal anything to him and it frustrated him greatly. Unbeknownst to you, he'd long developed feelings. Countless times at each others sides in battle, sparring sessions where neither was willing to surrender, and nights spent together sharpening weapons allowed for unexpected emotions to arise.
He allowed you closer than he normally would have and some stupid part of him began to think your connection was special, different than anybody else's. It wasn't long before he realized someone else had you in ways he didn't.
It was nighttime and he shouldn't have been up, but he was, and after working up a sweat to stave off restlessness, he headed towards his room.
But to reach his room, he had to pass Sylvain's. Nearing his doorway, Felix heard the creaking and shaking of bed springs. Rolling his eyes, Felix huffed, no doubt Sylvain had gotten someone under the covers, that man really is insatiable....
As he was passing the doorway, Felix moved to cover his ears to prevent hearing such raunchy sounds coming from the red heads room but before he managed to muffle any noise, he heard a voice he knew.
"Ah...Sylvain, don't leave marks there...they won't believe..ngh..the mosquito excuse in winter..."
Saying time stopped for Felix is cliche, but it sure as hell felt like it did. He'd only made it halfway past when he'd heard your voice, that voice that he'd grown accustomed to hearing whine when he'd interrupt one of your naps in favor of a duel.
Felix's footsteps halted and against his body turned towards your voice. It was just a small crack in the door but it was enough to confirm what it sounded like. He couldn't see Sylvain, but he could see you.
You were pressed against the bed, clutching at the mattress covers with your eyes shut, breathing heavily, cheeks tinted red from exertion. From what little could be seen, he could still tell your body was being rocked back and forth from behind, it didn't take a genius to figure out the rest.
He stepped back out of a misplaced sense of betrayal, and a cold sweat began to form on his forehead. Another moan from you jolted him back to his senses and he turned, walking quickly to his room, hating the way his body reacted to your voice.
He felt like a fool. A complete and utter fool. He knew he had no right to feel as though he was deceived, you didn't belong to him, and he didn't belong to you. What his best friend did with his time was none of his business, but his heart didn't care and it was pulsing with jealousy and a momentary loss for something that he didn't have to begin with.
He couldn't sleep that night. Anytime he closed his eyes he'd hear your voice again, this time begging for him to be the one to grab a hold of your hips and-
Ugh. How pathetic. He didn't need distractions like this. He'd known all along that anything having to do with romance was merely a waste of time, he knew that, he'd always known that. That night had ended with a cold shower and the constant tossing and turning till morning broke.
After that, Felix almost wanted to stab himself seeing the amount of signs that you and Sylvain had anything but a normal relationship, in plain sight. Sylvain's lingering gazes, his offers to do anything for you that would require extensive walking, the turning down of propositions from women??
Even you were acting different, the sudden preference for high collared shirts, the newly found interest in the same poetry and art that Sylvain had, and even your growing proficiency in magic was telling.
..And..He himself was acting different, it wasn't his place to be bitter but his mouth had no filter. Every so often, his usual tongue lashings would have more of a bite than they normally did. The confused looks the both of you gave him, wondering if you'd done anything to upset him, only made him feel worse
When the war hit, he knew your affair hadn't stopped, but he had bigger things to worry about then. He'd grown a lot, matured emotionally, forming an even closer friendship with the both of you, despite knowing of your relationship.
Despite his unforgiving feelings for you. He became a rock for you and Sylvain, on and off the battlefield. A trio who could wreck havoc, as Ingrid put it anyway. A twisted part of him hoped Sylvain's philandering side would make its reappearance, cementing that the two of you were only in it for the primal urges.
But, those hopes were dashed when Sylvain announced his engagement to you shortly after the war ended.
