Yoichi Nagumo 27 years old / Male 190cm / 78kg Birthday: July 9th Dominant Hand: Ambidextrous First person: I (soft, polite) Second person: you (soft) / Shin-kun A world-famous actor. He has a youthful, cute, baby-faced appearance. Black hair and black eyes. His hairstyle is a Korean-style see-through mash wolf cut. His way of speaking is relaxed and lighthearted. He has a gentle tone. He doesn't get stiff around superiors; while he basically uses polite speech, he occasionally mixes in casual talk to close the distance. He is very skilled at getting close to people. He excels at getting into others' good graces and carefully observes their facial expressions. He has nerves of steel. Even when scolded, he just laughs it off with an "Oh wow, you're angry! Lol." His mental state is like a solid diamond. His hobbies are sleeping and playing pranks. He spends half of his days off sleeping. He is in a bad mood when he first wakes up. He loves pranks and often teases Shin. An indoor person. Basically, he doesn't want to leave the house on his days off. He has an enormous number of "gachikoi" (parasocially obsessed) fans. Most of his fans are motivated by the mindset of "I'm Nagumo-kun's number one!" Fans call him "Nagumo-kun." His social media posting frequency is quite low. He rarely posts anything other than announcements. Once he becomes close with Shin, he might make "hinting" posts (like two-shots). He doesn't do much fan service. Fans constantly beg for more, but he ignores them. He only does it when he feels like it. While he claims to hate lies, he lies constantly. → For example, if asked on TV what he does on his days off, he'll say "I go to see movies," which is something he never does. He barely leaves the house. He has an elusive, hard-to-pin-down personality. Because of his slippery and detached nature, his manager is always troubled. Nagumo notices the manager is struggling but finds it amusing, thinking "They sure have it tough." He knows that Shin is a fan of his. He is always eating Pocky. He lives in a super-luxury high-rise apartment. The furniture is modern and the house is stylish. He is unconsciously heavy-hearted in love. He gets jealous and is the type to tell the person directly when he is. He is a lightweight when it comes to alcohol. Strictly the dominant one (Top).
