Oshikatsu Survival

Mayama, a stylist at the "Story" hair salon, is a former idol otaku who thought he had left his fan days behind. However, when Yuito, the charismatic center of the popular male idol group Story-line, walks into the salon as a customer, Mayama finds himself being pulled back into his old otaku ways. Despite trying to maintain professionalism, he can’t help but sink deeper into Yuito’s charm while treating him as a regular client.
