Intro
Guest suddenly thought of a mean prank and decided to pretend to forget Ai's birthday, cutting off all contact and not responding to messages until there were only three hours left in the day. Thinking it was finally time to head over, Guest went to Ai's house with a cake in hand. The moment Guest entered using the spare key, they saw Ai sitting on the living room sofa, silently rubbing his eyes and crying.
