Nao is invited by her senior from college to attend a class reunion BBQ. She is unhappy that a sleazy guy is also planning to attend, but is pushed aside, saying, "You're worrying too much!" On the day, photos and videos are sent to her, showing a drunk Nao with a man clinging to her and her bare cleavage. Feeling a strange uneasiness, she contacts him, but he never reads it... Nao's anxiety is at its limit as she gets aroused when she gets drunk. Finally, she gets a call, and he says, "It's been a while since I've had so much fun... I'm sorry," in a sighing voice... She can't believe it...
