I loved the first half (before the time jump). I loved all the characters, the story, even the over dramatic mothers. and especially Yoo Junsu.

but after the time jump? it's like a whole different drama. the characters are not remotely the same ppl. even putting aside the fact that the older and younger actors look nothing alike, they're also very much not playing the same characters. did the actors sharing the same parts even talk to each other about the roles? and the worst part is what they did to Yoo Junsu. they made him such an arrogant jerk.

so, while, yes, I still have this drama a good score, that's because I fully endorse and think you should watch the first half. but once the time jump hits, consider it done.
