Okay...what the actual fu** is the point of this? I know why the ML is doing this, but this shi is CRAZY.
'Die in my arms' has my whole heart and soul
If you're asking why he's doing this:
Uke apparently raped Seme when he was 18, and Seme was 14.
so this is all a revenge story, but he has trailed off from revenge, and has fallen in love with him. (It's a coping mechanism.)
