三沢 孝太

A meek and quiet student who is often asked for favors by students and teachers alike. One day, Ayaka was surprised and fell off her chair as Kouta tried to talk to her, which caused Kaoru, Ayaka's boyfriend, to bully him. Because Kaoru is popular, Kouta became an outcast in school before long.

To exact revenge on Kaoru, he downloaded a hypnosis app on his phone suggested by a friend from the internet. He then used the app on Kaoru's girlfriend, Ayaka.
