Im looking for drama. Female regrets cheating or leaving or rejecting the male lead. She then wants him back but the male lead falls in love again with another female "female lead" Example buzzer beat It can be korean or japanese or taiwanese
In My Name Is Kim Sam Soon, the second female lead come back from the States and she will try to get her boyfriend back. It's the same for Mary Stayed Out All Night. The girl wants her ex-boyfriend back. I can thin also of Full House Take 2, but the leading girl you want isn't really important from what I remember. Hope it helps :)
9 End 2 Outs Goong Oh! My Lady Pasta Sweet 18 Wild Romance
Oh gosh, there are so many with this kind of plot, but I second My Name is Kim Sam Soon. Great drama :)
When a man loves!!!
maybe Material Queen too :)
The Taiwanese drama Just You has the regretful ex-fiance, though she doesn't show up til the halfway mark.
