Because he said he was bored with the pornographic movies his roommate was watching, he was written as the protagonist of the "Eighteen Touch" series of "Little Yellow Mosquitoes", where he was touched and pressed again and again.
He didn't take it seriously, because the protagonist written by his roommate was completely different except for the same name as him, and he had no sense of substitution.
Then, he penetrated the small yellow mosquito.
Then, he discovered that what he passed through was a supporting character's rebirth and counterattack fanfic, and he was the protagonist who was counterattacked.
So sad.
