Mother's best friend

My mother's best friend, Maki, suddenly arrives at the house. Apparently they had a fight with the couple. Junichi ends up listening to Maki's complaints in place of her mother who goes out to work, but for some reason her love story has become a hot topic... Junichi, who has longed for Maki, is nervous and talks hard, but Maki teases her for being cute. Furthermore, Maki even kisses her, saying it's a practice that won't make her nervous, and stirs up Junichi.
