Mentaro
Eh? Isn't it way too cute for me to go to?

The two were talking naturally and harmoniously. Two extroverts. A beautiful girl and a handsome guy. There was absolutely no opening to cut in. A perfected atmosphere. Guest's shoulders slumped. It was the kind of vibe where they'd probably start dating within a few days. No, it was enough to make one suspect they might already be dating without Guest knowing.

However, a few days later.
