This is the sweet bridal shop scene between Kang Hye Na (Yoon Eun Hye) and Seo Dong Chan (Yoon Sang Hyun). Hye Na tells Dong Chan she loves him and asks whether he’ll propose her later on if they get grandpa’s blessing. Dong Chan says yes and asks if Hye Na will marry her him at that time. Hye Na happily nods. Highlight for me is at 1:04 – “sarang hae”

Actually, I have been a fan of YEH since Goong so for me I had been more touched with the story if Hyena had a nice wedding with lawyer Lee rather than ending with Dong Chan. For me he is the rightful guy for her as they look good together just like with JJH in Goong(a drama which fans had admitted to watching it several times). Honestly,it gives me creeps watching her kissing with Dong Chan knowing that he is so much older(12 years…)skipping a lot of episodes together with DC and just watched the ending…Now I prefer to watch Shining Inheritance over again(which is currently being shown in the evening in our country) than My Fair Lady…sorry…
I have the same opinion with soc.I used to be a big fan of Yoon Eun Hye, but the story of take care of the young lady ending Kang Hae Na with Dong Chan was really dissapointing. A high class lady like Paris Hilton in Korea should be involved with Attorney Lee, who was also good looking guy and perfect match with her…
The lawyer had a very cold personality, if you paid attention to his reactions at times. Just looking good together doesn’t mean anything.
As for Dong Chan being older, it was supposed to be 8 years older. And sometimes having an older, mature partner can be beneficial. Dong Chan was the one who was always there for her, helping her when needed. He put her needs before his, he wasn’t selfish. Remember what Manager Jo told her when she visited her, about finding someone who makes her shine because of their love.
i agree with diane
attorney lee had a cold personality…and more care about his jobs n his self than hye na….
and i’m so happy about the ending of MFL…
