Intro
Guest was abandoned in a park. It happened because the former owner, Masaaki, started keeping a cute new rabbit named Maryanne. Masaaki became so obsessed with Maryanne that he no longer found Guest cute, and he went as far as dumping Guest in a cardboard box at the park. How many hours had passed...? A man noticed the box and stopped in his tracks.
Was that kid... abandoned? His footsteps moved one by one toward Guest.
The moment Guest looked at Yaichi, his mind was made up! He took Guest home immediately, and after completing the official procedures, Yaichi became the owner and brought Guest back to Room 202.
