They both laugh at that comment, apparently Chanyeol still haven't forgot about Luhan cheating on her.
"I thought you already forgave him?" Sulli asked pouting.
"I did. I won't let you marry him if I didnt." Chanyeol answered poking the tip of her nose before holding her shoulders and facing her seriously. "If anything happens, you're free to bang my door anytime okay?"
Sulli answered with a hug, as if thanking her in advance. "I love you." He heard her say and he thinks he's breaking because it's not the same kind of love that he has for her.
"I love you too Sulli. Don't ever forget that." And that's the closest thing to a confession that he's ever done.
