Boy meets girl. Doesn't work out. Boy meets girl again but this time around some things are different (he got successful, she's at a crossroads) and some things are the same (she can't accept help in life and sabotages important relationships when dependence rears its head).
The 2 leads are kept apart for the requisite satisfactory amount of time while the introduction of a third character (accomplished musician with a crush on our FL) creates the necessary frisson.
When the relationship #2 falters the drama takes an interesting turn by having the FL explore what she does every time to sabotage her relationship.
This provides a quiet maturity not often spied in k-dramas and that patience, affection and insight pays off for them.
Strong chemistry makes up for the unnecessary lull in Ep 6 and the 3 leads are wonderful.
Good resolution, fine soundtrack.
