Again my life - Teeny tiny romance. Only in the final episode, and only mentioned like once, so definitey not noticible.
Angry Mom - The fl is married. But there is no focus on romance whatsoever. Only about her relationship with her daughter.
Jirisan - No romance at all.
Kairos - The ml is married. But his relationship to his wife is not romantic at all. I would claim that there is zero romance in this.
Mother - No romance at all.
My Name - The romance is very very slight. This is very much a revenge drama and little else.
