The daily life of a son who fell in love with his mother's best friend, Yuri, suddenly changed to a rosy color. - I want to get Yuri's attention somehow, but my son, who has never talked to me, let alone experienced women, is just spinning around. - The son who is at a loss comes up with the idea of making Yuri's underwear smut at least to make memories. - She is found by Yuri, who happened to be there, but instead of getting angry, she kisses me gently.
