My aunt came to me on a dating site.

Yuta is given the entrance exam to be placed in her aunt Mizuki's house. I thought I would start studying, feeling nervous and faintly excited about living under the same roof with a woman other than my mother... He secretly makes an appointment to meet an older woman on a dating site he learned from a friend. I was nervous and came to the meeting place... Mizuki was the one who appeared there! Although she is upset when she finds out that her partner is her aunt, she asks Mizuki, the woman she admires, to take her first time with him...
