'Minority'-- do not go on the name, the story is genuinely good

'Timeless Melody'

'This ending'-- this ones supernatural a bit but the emotions are realistic I'd say

Idk what your definition of realistic is, but here are some that come to mind. I'd say the relationships, conversations, struggles and dynamics are pretty realistic.
P.s: aside from the last one, rest of them have great dynamics and the relationships are on the healthier side (and no r*pe btw). And even in the last one, the ML does a decent job at redeeming himself.
