Just in case anyone sorts by new trying to find the intro song search this - Chiisana Koi no Uta - I would suggest using the japanese version with subtitles instead of english cover it just sounds better. :) P.S. The second song before ashite is - 約束 or Promise - very beautiful as well.
Bro I hate it when people like interrupt someone doing something like Deku was doing and then interrupt them to be like “I don’t understand!?” LIKE IF YOU SHUT UP MAYBE YOU WILL FIGURE IT OUT
I feel like the kid is about to unalive himself... I mean, he is calling (assuming Baku since they have a love history) "sweetie", as if going back and enjoying the past for a little before he goes, or as a way to try to grasp on to that little sweetness Baku has ever given him. and he kept saying "sayonara", along with the reference to exiting the fairytale, assuming this fairytale is his life then he is exiting his life (KHS), setting himself free from this madness. and right now, he is just saying his last goodbye to his sweetie, despite how much baku hurt him he still loves him (unhealthy relationship?obsession). the torture could be referring to his own inner-conflicts; hero or villain, forgive or revenge. Captivity could be referring to his feeling of being trapped in his own conflicting mind, and/or his past and love history with Baku that he can't seem to let go. BUT ofc this is just my interpretation XD
