finally having read sqh's pov in the extras and getting a clearer image of mobei jun is realising he's the same as binghe except their abandonment issues manifest very differently, in that they're the same but they're equally opposite to one another too.
luo binghe's abandonment comes from having a single parent and losing her and then being tossed around and abused his entire childhood while growing up poor, and then pushed into the abyss. mobei jun's abandonment comes from a severe lack of parental figures and a sense of security where the one demon he trusted the most was the one who broke him down into nothing by leaving him alone in a completely new world and getting hunted and captured for days before anyone even realised he was missing.
binghe seeks out connection because growing up lonely and having received kindness and love, even at the bare minimum level, while growing up changed him fundamentally and in a way enabled a very deep rooted belief that once someone loves him so sincerely, he'll never be loved like that ever again. it only makes sense to hold on to it. binghe's feelings come from a place of devotion and unbridled passion.
mobei jun on the other hand, grew up with everything, except love and kindness, his betrayal from the most significant person in his life changed him fundamentally in ways that taught him at a very young age that being alone is the safest way to be. mobei jun operates on fear and intimidation to avoid any vulnerability whatsoever, but moreso, the only way he could have a semblance of trust in anyone comes strictly from a place of duty or obligation to him specifically. his fear of being betrayed essentially boils down to, "can't be betrayed if i don't rely on anyone or let anyone else in."
luo binghe's abandonment issues leads him to be possessive and codependent, while mobei jun's abandonment issues leads him to be hyper independent and avoidant. binghe would much rather die than be alone and mobei jun would much rather destroy than express any vulnerability.
in all of this, there is a desperation under both of their facades that longs to be loved sincerely and completely, allowing them both to let their guards down and rest for once. there is also a naivete to both of them and their emotions, i won't go into much detail abt binghe cause it's already been severely discussed but mobei jun is mostly scared of being betrayed again, it's easier to scare people into submission, but more than anything, in his dynamic with shang qinghua, he constantly only quotes one sentence over and over again. "my lord I'll follow you for the rest of my life." as a frequent reminder to shang qinghua and sqh even confesses to himself at one point that it was just something he said to guarantee his own safety, he didn't expect mbj to cling to it like an oath. but he does and sqh's word alone after so many years is something that's reassuring to him, he, like binghe, needs frequent reassurance that he's not being left behind. but if he receives even the tiniest shift in that promise, he'll completely freeze sqh out. his attitude and behavior towards sqh does an immediate 180 and he'll completely shut him out.
mbj, like binghe is also incredibly loyal, in that, sqh mentions how mbj is great at protecting him in return and that he often showed up whenever sqh was in trouble. We also see an instance where sqh runs into linguang jun and being scared out of his mind, he screams out for mbj in desperation, in spite of the fact that he was running away from him. mbj shows up immediately, without the slightest bit of hesitation.
