Haishin Game -#Mezase! Kami Erotuber-

Synopsis

The main character Fujita is an "erotuber" who uploads "live sex toy reviews," with the help of a paid amateur AV actress, to an amateur porn site, under the pseudonym of "FIN". He's pretty famous there, but in class and real life, he's a total nobody. Popular gyaru girl Rei knows about this secret as, one day, he tried to upload a video secretly filming her underwear, so she uses that to blackmail him into editing her Insta photos. Eventualy, the girl he worked with retires of acting and, just a few days later, the website announces a really huuuge prize for the most viewed video that month, so he tries to convience Rei of being her new actress. She ends up accepting, suprisingly, so she can pay for clothes, modeling classes and more things her parents don't pay for her. Thus, the race to reaching the top starts for the two of them, changing them in the process.
