As Baekhyun ate breakfast, he kept thinking about Kris.  He was so absorbed in his thoughts that he did not notice himself drinking water. 

At the same time, Chanyeol came in and asked him, “What are you thinking about?” 

With water still in his mouth, Baekhyun replied, “What?  Oh nothing!” and nearly choked on it.  Chanyeol said to Baekhyun, “Are you okay?  Ah hah, that sounded like woongya woongya!  Kris…” 

Baekhyun suddenly lost his appetite, and Chanyeol’s face no longer could be attributed to the happy virus.
