i feel like a kid getting presents on christmas lol thank you anon!! yanbettel food i eat out of the palms of your hands gratefully!! currently am listening to the song on repeat while replying to this prompt!
let me just say rq holy shit this song bangs. the metal scream bridge? and then being followed up by a slow down and then it goes back to the chorus?? holy shit. shit is GOOD. the way the song is laid out like its own story and journey definitely gets me thinking of yanbettel too...

"I felt it—it was destiny. Mutual love. I won’t hand you over to anyone! ☆...Jealousy and lies are proof of my love. Darkness and wounds, too, are proof that I love you....I’ve been addicted to you, only you, my whole life!"
the first part of the song where yanbettel sees hakka and starts falling for him, starting with normal yearning and crushing, but then somewhere down the line he gets obsessed, his love for hakka mixing with possessiveness and urges he knows he shouldnt want when it comes to those he loves, but he just wants hakka by his side all the time!
i also really like the side parts "(I want you to figure it out) (So you finally figured it out)" in the song, like yanbettel knowing of that sick twisted part in himself and deep down, wanting hakka to see it too, wanting hakka to figure out the worst darkness in yanbettel. part of yanbettel is terrified to let hakka in and show that part of himself because he may run away, but yanbettel doesnt have a choice when another guy comes into the mix and he starts getting jealous, wanting hakka to see him and only him

"Looks like you’re having fun with that girl today, too. When’s it my turn?...Well then, since that girl and the other one, too, are all in the way..."
then to the metal screaming part of the song, and this is where yanbettel snaps and gives into those evil urges in him, whether that be killing someone else who has been flirting with hakka, or maybe he kidnaps hakka and ties him up to keep for himself, OR BOTH.

then the song slows with soft singing like pleading, and this is when hakka wakes up, cold, terrified, and tied up in yanbettels basement, yanbettel holding his trembling hands and promises hakka that he wont ever have to worry about anything again because he will always be at yanbettels side and he will protect him! yanbettels eyes shaped into little hearts when he gazes at hakka, finally showing his true self and true feelings for hakka

// self harm
"I won’t get any more lies or cuts on my arm, will I? Promise?"
ough yanbettel most definitely uses every manipulative abusive tactic he can against hakka which includes hurting others and himself too. everytime he sees hakka talk to another guy, bettel gets so upset and jealous he cuts himself and sends hakka a photo to make him feel guilty, saying how its all hakkas fault that he did this to himself
