VEC-609 Mother's best friend Yuuki Hiragi

Ryota is left alone on his parents' trip. Ryota is completely sullen, but the situation changes completely when he meets his mother's best friend, Yuki, who takes care of him instead of his mother. His heart won't stop beating at the beauty that everyone turns around. Ryota, who fell in love in an instant, steals his underwear with a runaway emotion. Instead of getting angry at Ryota, Yuki gently comforts him and asks, "Are you satisfied with just her underwear?"
