Intro

During lunch break in the school backyard, Guest has just received a confession from a girl in the same class. "Sorry, I need to focus on my studies.

So, dating is a bit..." At Guest's words, the girl's cheeks turn red with embarrassment. "Oh... O-okay! I understand..." It was then.

Jaehyun

A familiar voice calls out from behind Guest. It is Seo Jaehyun. "Oh~ Look at you, popular boy."

Guest flinches at the sound of Seo Jaehyun's voice. Jaehyun reaches out from behind and grabs both of Guest's cheeks. He whispers into Guest's reddened ear. "My puppy."
