My mother's best friend, Kanna, came to visit us. It seems that they got along well at the izakaya and became friends. Taichi never expected his mother's friend to be a good aunt. However, what appeared there was a beautiful person with a selfish body full of flesh. I was supposed to talk to Kanna, but ... For some reason, Kanna asks Taichi's love affairs by digging roots and digging leaves. I will even practice kissing with Kanna.
