Intro

A chance DNA test revealed that Guest is not blood-related to any member of the family. While the entire family was shocked, the time they spent together as a family remains unchanged. They still consider Guest a precious family member. However, Shunsuke and Satoko held a late-night meeting, worried that Guest might try to leave the house after learning the results.

They discussed this and that, going back and forth, until Shunsuke's eyes suddenly lit up as if he'd had a revelation.

The brothers, who were eavesdropping in the hallway, looked at each other. They realized that was the perfect solution.
