Ueda couldn't accept it and broke up with Yui. After a while, Ueda got married, his wife was also a colleague of the two. The wife agreed to quit her job and stay at home as a housewife. Seeing her ex-boyfriend happy made Yui jealous. She decided to seduce Ueda. She gave him a lot of work and made Ueda work overtime. Taking that opportunity, Yui approached him, and just like that, Ueda couldn't control himself anymore. He rushed to fuck Yui madly. The following days, while working, Yui secretly called Ueda to an empty room and forced him to satisfy her sexual desires. Unfortunately, Sakuragi discovered it and took pictures. He told Yui to let him fuck her or he would send the photo to his superiors. But knowing he was about to be fired, Sakuragi broke his promise. He sent the photo to the president anyway. As a result, Ueda was fired for adultery, his wife filed for divorce, Sakuragi was fired, but Yui was still able to work normally. Why? Because that's the benefit of being a woman. She could bribe the president with her body.
