Seungwoo became silent. Not knowing what to do, he decided to turn the engine on and drove on the way to their neighborhood. After they arrived at their house, they bid farewells and went on to their lives. He went home; Suji's words were stuck on his mind like bubblegum, and he couldn't help himself feel bitter.
After he rejected Suji big time, he felt sudden extreme feelings of guilt. But he tried not to feel that way and continued to treat her the way he felt like it. Anyone can see how much he valued her, and anyone could tell how much he was interested in her no matter how much he tried not to.
All he wanted was to keep being friends and keep their relationship not more than that. But he knows how impossible it was for Suji.
