I need semes who messed up bad with uke and are on their knees begging and filled to the brim with regret. I've read BJ alex, Limited Run, The World Without You and Can't Think Straight.
Low tide in Twilight has a good groveling ML but it also has a lot of t/w. So check them before starting. And Try Painter behind the curtain, The wife is first, Neon sign Amber, Smells like green spirit, Form of sympathy, To take an enemy's heart, For my weirdo(check t/w), I would recommend Erha too but the manhua is stuck. ╮( ̄▽ ̄)╭
Ok but how cute is that Alpha mom who gave the "no body in my family has ever been an omega!!" ended up trying to be as supportive as possible (albeit overbearing) Totally thought it was heading to a disappointed parents cliche
