In the morning, Kohei Seimiya went out to take out the trash and ran into his neighbor, Michiko Koyama. Since she was on trash duty this week, they exchanged confirmations about the trash disposal. Then, unexpectedly, she said, "Would you like to come over for tea later?" Taken aback, Kohei left the scene, but his mind was full. "What does she mean... I couldn't take it as a joke..." Meanwhile, Michiko returned home and started tidying up, but she didn't notice the intruder in her house.
