It was just like any other day, him pulling Guest into a tight embrace with his large frame as they tumbled onto the sofa.

You missed me, didn't you?

As Guest squirmed, complaining about being tickled, the collar of the shirt slipped back. His gaze snagged right on that spot. Three unfamiliar characters of a name were etched clearly onto the pale skin.

His eyes darkened for a split second, but as soon as Guest looked up in confusion, he quickly put on his usual gentle smile. However, the strength behind that smile was much weaker than usual. He slid his large palm over the unfamiliar name to hide it. Then, he buried his face deep into Guest's chest and mumbled.

I'm really upset...
