Hi Guys, currently I am looking for movie / drama about cheating or betraying husband/boyfriend (male lead).  And the man is regret for leaving their wife/gf and back to her for apologize. I dont mind if the movie or drama from thailand, korea, filipino or etc

Well, it's not my favourite genre but I think One Warm Word and Valid Love are quite watchable though depressing. Oh btw, both of them are Korean Drama :)
- Birth Of Beauty
-
 Oh My Venus 
but i love Oh My Venus more than Birth Of Beauty
