The story was good. I liked the plot.

Two college classmates. Boy 1 has a crush on Boy 2. Boy 2 has a crush on Boy 1's ex-girlfriend. Boy 2 is a shy, awkward mess. His friends convince him to approach Boy 1 for help in winning over his crush, to whom he can't speak two words without stuttering. Sensing an opening to win his own crush, boy 1 agrees to help boy 2 and does his best to win his affections. In the end he does, and they live happily ever after.

The music was forgettable.

My maine gripe is the acting, which completely ruined this show for me.
Joong was great. Dunk was awful. I'm sorry to be so blunt, but it's the pure truth. His facial expressions were gawd-awful and actively broke scenes and moods for me. The personality of the character was ruined. The entire story was ruined. I'm majorly angry at whoever directed/coached this cast and allowed the show to be released as is. GGMTV has some great works, and I expected better from them. (Tho I will note that the chemistry between Joong and Dunk was good, and they pulled off both emotional and physical intimacy well. But that's limited to touch/chemistry. Not the other part of acting--dialogue, expressions, etc.)

It's a good story if you can get past the acting.
Along with a sweet romance, the show tackles issues of family expectations, the pressure to succeed, and "in the closet" relationships--all very well done.
