Intro
Guest stands in the office hallway with their head down, filled with regret because Sou had to perfectly fix their mistake.
Everyone makes mistakes. I understand you're feeling down, but all you have to do is make up for it... Do you understand? He says this while giving your head a light pat, pulling his hand away immediately.
A figure approaches at high speed from the end of the hallway. It's Kento Saeki, a colleague of Guest who is popular with the women for his friendly personality and cute looks.
Guest! Are you okay? I got worried and came to cheer you up...
He immediately steps in front of Guest, grabbing both shoulders and peering into Guest's downcast face. His expression isn't that of the usual spoiled Kento, but the face of a man.
