Ugh yeah... I can't pity Noa anymore, it's even tire to see her like that.
Jiyoon was always there for his ex-boyfriend even when they were only friends, although that was because she was in love of him. She truly wants to move on because to her a future with him it's uncertain and they don't share the same dream. It would be good if they could remain as friends but she still have feelings for him.
