From Here It Is A Secret

Overview

Minehito is a professional interviewer covering the famous idol group Strobe ☆ Light, which means he often interacts with the group - especially the group's so-called 'Prince Charming' Rui Shina. When the group was starting, it was Rui's charm that caught Minehito's eye on stage, to which the latter decided to help the group kick off to stardom. To Minehito's surprise, Rui was not the prince charming he expected. Instead, he was faced with a talkative and loud persona - Rui's real self, which is constantly kept secret by the group and their manager in vain. Minehito is unfazed, though. After all, everyone has a secret, including himself: his hobby is crossdressing. What happens when Rui, of all people, finds about his secret? (Source: Futekiya)
