Katsu fell in love at an important time before taking the exam. The person I'm interested in is Yu, my best friend's mother. I never thought I would fall in love with my best friend's mother. Katsu is worried about Koiji, who will walk on the thorny road no matter how he falls. When I go to my best friend's house almost every day, I just want to see my face at least ...
