Diavolo's possessive nature♕
and honestly? it isn't talked about NEARLY enough.
Like- I know all characters, when romanced enough display some kind of possessiveness over MC.. but Diavolo... his possessiveness is treated more as a right he has.. rather than an offer.. This man is the perfect manifestation of pride and envy in one.. especially when it comes to MC Once you give the big man more attention.. more love.. he almost clings to it.. after all, his extremely lonely past in almost complete isolation.. tied together with this busy life as the prince of Devildom. Having at least someone.. MC.. care for him.. even a little.. and getting to know a side of him he almost completely keeps hidden from others, out of the protection of his ego, as a future ruler - a symbol of strength of Devildom.. its something he just can't let fall into someone else's grip.. As a true demon.. he is able to control his possessiveness - unlike the demon brothers who are new to strong demonic emotions such as possessiveness over things.. however this control - only makes his feelings 1000 times stronger and much harder to deal with...
" Honestly, I'd like to lock you away and keep you for all of eternity "
when Diavolo confesses his strong feelings to you, he really means it.. like really. and coming from his mouth, it was more like a demand - rather than a confession. he's the prince of Devildom for fucks sake.. and to him, in his mess of pride and envious tendencies and desires.. he feels like he, and he alone should have you.
and to be honest? he KNOWS no one has the authority to stop him.. and that only further, strokes his pride..
However, at the bottom of his sinful heart, he knows he can't take it upon himself to do that to you... he respects you so much.. he just hopes you chose him... actually scratch that. he KNOWS you will... and he will make sure of it.
