Not Found Love

Having Feelings for My Friend...? (1x8)

:

I-Seul comes home and tries to remember what exactly happened between Sang-Woo and herself with her love journal. She had to move toward Sang-Woo every time. I-Seul and Sang-Woo texts each other, but he has not changed at all. He does not want to change but her. She realizes that it is the wrong answer again. "Even if I changed myself, it would be the same if the other person does not change."
