Ryota was left home alone due to his parents' trip and was feeling down. Suddenly, Yuki, his mother's close friend, arrived to take care of him. Struck by her beauty, he instantly fell in love. Overcome with excitement, he stole her underwear, but instead of getting angry, Yuki gently comforted him. Then she boldly asked, "Are you really satisfied with just the underwear?" In that moment, Ryota's heart was shaken even more.
