Still 17 Episode 10

Both Chan and Woo Jin slowly start developing feelings for Seo Ri. However, unlike Chan who accepts and enjoys the way he feels toward her, Woo Jin seems to be anxious about the fact that he may be tangled up in someone’s life again. One evening, he spots Seo Ri looking at the moon and making a distinct hand motion that he remembers from the past. Suddenly, he starts panicking, and the flashbacks from long ago come back.
