Unreasonable turn in this movie .All I can say it is one-time watch .Twist in relationship .Boy and girl fall in love know about the matter that their parents switch the partners and getting married then twist enter which lead to sad and slow story and the truth is unfold with the truth at some point I got confused ,now I am not understand that their parents continue their relationship with switch partner or for their children sake they remain with their original partner.complicated ending .Maybe I got confusion because I didn't understand last part of subtitle well or may be not.
