When I Became the Manager of Popular Streamers, All of Them Were My Ex-girlfriends

Kei Tachibana is hired by a company that undertakes managerial duties for famous streamers. He is in charge of three popular streamers. Ayane Hayase, a cool and mature older woman who once aspired to be a model and has the perfect looks that attract the support of many female fans. Touko Kaga, a seductive streamer who has millions of male fans and has been banned four times for her erotic ASMR streaming. Mei Nako, a VTuber who, despite her childish voice, has a natural talent for attracting men and has driven them crazy. These three streamers had one thing in common. "Please make sure you don’t cause any problems in their private life. If there are any rumors about the three of them being romantically involved..." Ayana had overwhelming support from women, while Touko and Mei had the support from men. Rumors of romance were not allowed. But...

Kei wanted to keep his past relationships hidden at all costs, but his relationships were being probed from all sides... (Source: Kakuyomu, translated)
