Fatso has an earphone that can make people within 2km radius think what the fatso is doing is normal (i.e. "ninshiki sogai" kind of hypnosis). Fatso use it to have sex with girls at school (pg 2~9). Fatso lost his earphone.
MC picks up the earphone and gain memories of what actually happened (pg 10~16). MC punchs fatso and vow to protect the girl he likes (pg 17).
MC ends up fucking her (lol) and confess mid sex (pg 18-28). Girl rejects and reveals she actually has a boyfriend (pg 29-33).
In the end, MC decided to disable the hypnosis after thanking her (for her honest reply).
