I`m looking for the name of a drama.I didn`t see the ending.?

Two sisters moon-hee and jee-hee fall in love with the same guy, min-sung. Min-sung likes moon-hee since they met first. Jee-hee tries to make her sis jealous.Somewhere in the middle jee-hee faces the facts and supports her sister by sewing her wedding dress.She accidently tears it so she gives moon-hee her own wedding dress. Moon-hee and min-sung get married. Also they find out that their real mother was a famous woman (who i think is an actress). Jee-hee starts living with her real mom. I tried looking for this drama but can`t find it..
