Minamo is a very sociable person, close to other colleagues in the company. Yuzuru, on the other hand, always builds a barrier between himself and others. Today the company organized a party, seeing Yuzuru standing alone drinking, Minamo approached and started a conversation with him. Both felt the party was quite boring so they decided to leave early together. But because they missed the last train, Minamo suggested they stay overnight at a hotel. "What do you do when you go to a hotel?" Minamo took the initiative to "invite" Yuzuru. It turns out that Yuzuru always acted like he didn't care about Minamo, which made her curious. She approached him purely for sex, with no other intentions. At first, Yuzuru felt the same way, not wanting to get involved in a relationship with someone else. But as he got closer to Minamo, he found her more and more attractive. When he realized he was in love with her, he discovered that Minamo had many other "bedmates." Yuzuru felt jealous, and jealousy clouded his judgment. When Minamo came to Yuzuru's house as usual, he forcefully had sex with her, but this time without protection, ejaculating inside her womb! Right after that, Minamo quit her job and disappeared from everyone's sight. Yuzuru still remembers her, the only girl he loved...
