I mean, hear me out. 1) Legal 2) Care for the little bro. 3) IKKEMEN 4) I don't know, FIX EACH OTHERS SOMEHOW. I mean. I'm having a hard time sinking the main ship because the age and I'm desperate for some "rivals into lovers" instead of that jail-baiting.
"People are usually lovey-dovey". Bruh, Just tell her she is not generic enough for you.
