Chanyeol is a sad, sad person, and Baekhyun makes him happy again. 

He hasn’t forgotten those arguments, those worries. He hasn’t forgotten his desperation, his dread of the next silent, cheerless day. He hasn’t forgotten long nights of crying himself to sleep, or the inescapable cold of the park and freezing of his fingers, hoping he’ll freeze up and fade away like the flowers. He hasn’t forgotten what it was like after Kyungsoo and before Baekhyun.

But he doesn’t feel any of it. He feels happy.
