Chanyeol feels his heart beat a little too fast. 

Why?

Everything Baekhyun does makes his chest flutter.

"Baekhyun," He stuttered as he put the other's hand against his chest, "Do you feel it?"

The shorter nodded his head, cheeks flushing a shade of pink. "I do... It's quite fast."

Chanyeol smiled and said, "160 beats a minute, Baekhyun. It's all because of you,"
