I recently watched Missing you and I was in love with men obsessed in love with the main female. I saw obsessed the movie, chuno, boys over flowers, summer's desire, the greatest love, a thousand years of love. It does not have to be Korean. I took a liking to Asian men. I live in America so I am new. Missing you was what I want. I am now bored from seeing it alot. I hate obsessed women. I love obsessed men. They are better.
p.s. No historical dramas. I hate chuno. Also, I do not like comedies when it comes to obsessive love. It has to serious matters.
By obsessed, I assume you want the jealousy and angst due to it... Not much of that in in K-dramas...Maybe: --- Que Sera Sera
Tons of it in C-dramas (but u don't want historical): --- Sealed with a Kiss ... He defines the Obsessed Male! --- Too Late to Say I Love You .... Very obsessed, not a perfect hero,passionate love. --- Loving, Never Forgetting ... well, she was obsessed, but he acted on it, he was jealous, possessive.
T-drama: --- Meteor Garden ... Taiwanese BOF / HYD .... Ultimate obsessed Male!!! ...Possessive, passionate, with all the jealousy, angst, etc...
