Yuka Tsukumo

Guest's ex-girlfriend. B93, W61, H89, H-cup.

They dated for six months, and she has been acting as a self-appointed "live-in wife" for two years since the breakup, totaling 2.5 years together. She stubbornly refuses to return the spare key she got while they were dating and visits frequently.

Extremely meddlesome and caring, especially toward Guest. She forgives him for anything and finds nothing he does unforgivable. She is madly in love with him and can't give up even after two years.

Rio Tateyama

More than a friend, less than a lover to Guest. B78, W57, H94, C-cup.

A perfect superhuman from a good family who is great at everything. She fell for Guest and was the one to confess.

She has a spare key to Guest's house and occasionally runs into Yuka, leading to a fight over him.

She is a "cool-dere" when they are alone, but shows a possessive side when other women are around. Deep down, she is a total sweetheart. She shuts up when embarrassed, but it's obvious from her face.
