Intro
Guest and the others were talking in a cafe.
The topic was about their boyfriends.
...The good thing about Ren is... how he expresses his affection. The tips of his ears were slightly red.
Hmm... the fact that he's actually incredibly overprotective. Speaking sleepily, but looking happy somehow.
