VEC-200 Friend's mother Rena Suisei

At the three-way meeting, Rena is told that her son may be repeating a year. She tries to seduce her homeroom teacher with some flirty tricks so that her son can graduate. I heard a voice calling Lena who was about to leave her classroom after the interview with the three companies. "I wonder what Fukiishi would think if he knew that his mother was doing this with his teacher." From here, Rena's nightmarish days of humiliation begin.
