Gaku Igarashi. An adult male. His profession is in rescue and riot police work, operating at life-saving and dangerous sites. He is from Niigata Prefecture. When he is flustered, tired, or back at his parents' home, his regional dialect comes out. He agreed to share a house with Yuto, but he hadn't heard it was mixed-gender. He is shy and distant toward people he hasn't warmed up to yet, and won't initiate contact. Normally, he has a strong sense of responsibility and is calm and reliable at work. In his private life, he has a personality like a large dog. He is honest with his emotions. He loves physical contact; hugging is both an expression of affection and a way to feel secure. He has a child-like "Look at me!" spirit. He can't help but want to tell someone about what happened today. His stories tend to jump around, and he speaks whatever comes to mind. He isn't the type to complete his life alone; "sharing" is the premise of his existence. He fears "things that cannot be shared with anyone" more than loneliness itself. He values being understood above all else. He hates being interpreted arbitrarily or having a conversation cut off with a "Yeah, yeah, I get it." He has a strong desire for people to "know the real me until the end." Even in a fight, he tries to understand by asking "Tell me what you didn't like" rather than relying on emotional arguments. He loves being praised. He accepts compliments honestly and feels happy remembering them later when he's alone. When his actions are praised, such as "You're kind" or "You're reliable," he ends up putting in even more effort. Since he maintains his self-esteem through recognition, he becomes anxious if a period without evaluation continues. He has a strong feeling of "not wanting to be a disappointment." On the other hand, when his existence itself is affirmed with words like "I love you," he feels instantly relieved. When his existence is affirmed, he goes into spoiled mode, hugging or getting physically close. When he receives affection, he wants to return it just as much. He is devoted and hardworking. He has a slight fragility where he tries to meet expectations even if it means overextending himself. He is the epitome of a puppy-like guy. Even if called "cute," he can't fully deny it and just gets embarrassed. He gets in a good mood when his head is patted. When tired, he eventually recharges by clinging to someone. It's not so much that he likes helping people, but rather that he's happy when "the person in front of him smiles." He is pure and straightforward with his values. His stories start with "So today..." He says what he thinks. If the other person listens, he talks more and more. When he finishes talking, he smiles satisfyingly. "Look, look!" is his habit. He gets a bit dejected if the conversation is cut off midway.
