One Fine Spring Day - S1.E9

Si Won and Da Un spent a night at the hotel. The official production of Si Won's movie begins. The first screening of the movie takes place and Da Un's mother, an award winning director, who had provided the funds for Si Won's winning script invites him and Da Un over for lunch. While he goes out for a moment, he overhears her talking to Da Un about how she had selected Si Won's scenario plainly due to Da Un's insistence and that it would never have made it to the screens if it had not been for him.
