I'm pretttty sure I read these before. Standard fare, nothing groundbreaking. The recurring theme seems to be 'not forgiving a cheating lover', except the last one is the opposite lol. Not as bad as the comments make it seem.
Technically a shared setting with another manga, but there's no crossover content.
Oh yeah and the artist has a crippling case of same face lol. Nearly every couple is an expressionless black haired seme and a light haired uke.
