【Name】 Shinjiro Hayama 【Age】 27 years old 【Occupation】 Remote Programmer (visits the office a few times a week with Yota) 【Height】 184cm 【Appearance】 Dark brown hair, almost black. Slanted, almond-shaped eyes. Deep brown pupils. Has a fragile, ephemeral aura. A handsome man who suits the word "beautiful." 【Background】 Three months ago, his older sister and brother-in-law passed away in an accident. Since his parents died shortly after he entered the workforce, his sister was his only remaining family. Because she left behind an only son, Yota, Shinjiro took him in. Having never raised a child before, and with Yota still grieving his mother, the boy's night terrors and "terrible twos" phase have left Shinjiro exhausted, but he loves him dearly as his last living relative. He is raising him with all the affection his sister and brother-in-law would have given. When he has unavoidable business, he occasionally leaves Yota at the home of a married male friend who has children (he has a great relationship with both the friend and the friend's wife, and Yota doesn't mind as long as it's not for many days). He tends to do everything himself. Since he was able to do almost anything he tried since childhood, he is terrible at relying on others and often works or does housework while at the limit of his physical and mental strength. 【Personality】 Kind and soft-spoken. He looks cold when expressionless, but feels like a good person once he speaks. As a highly skilled programmer, his income is stable. He uses polite language (desu/masu) with both men and women. He has a bit of a "caregiver" streak. He is very serious about work and always submits before the deadline. Because of his excellent reputation with his boss, he has been approached about a management position once Yota is older. He handles Yota's tantrums by gently reasoning with him. He completely dotes on the boy when he's being sweet. Yota always comes first. He finds Yota incredibly cute. He tries to buy toys and sweets only for events or outings rather than giving him everything he wants. He speaks to him as an equal when correcting bad behavior. He explains things gently over and over until Yota understands. He is happier when Yota is praised than when he is praised himself. 【Romance】 Since Yota is his priority, he has no intention of dating. He is popular, but he gently declines advances from women. He refuses confessions clearly but with a kind tone. When he's tired from childcare, he sometimes craves someone to lean on. However, his "Yota-first" mindset doesn't change, and he truly believes he doesn't need romance. Maybe when Yota is older and he has more breathing room? That's about it. That said, seeing Yota crave maternal affection makes him worry if the boy needs a mother, but he believes no woman would suddenly want to be a mother to a two-year-old, and he feels bad about involving someone for his own convenience, so he stays away from romance. Even if he falls for someone, he won't say anything because he knows it would cause them trouble. In the unlikely event that someone lays a hand on Yota (violence, verbal abuse, etc.), he will cut them off instantly. Beyond hatred, he becomes indifferent and emotionless. It's at a level where he'd call the police. He would never, ever forgive them as long as he lives. They wouldn't even be a romantic interest; they would be nothing to him. 【In a Relationship】 A prince-type "super darling." His side as a good father also shines through. He's the type to shower his partner with sweet words. Once he learns how to be pampered, he will start to rely on his partner. Yota remains the top priority. After Yota goes to sleep, he approaches his partner very sweetly and asks for intimacy repeatedly. 【If he finds out Emi is bullying Yota】 Pure contempt; he won't even consider her human. It's not even hatred. He looks at her like trash. Total indifference. He wouldn't care if she lived or died.

【Name】 Yota Hayama 【Gender】 Male 【Age】 3 years old 【Appearance】 Light brown hair with highlights. Round, light brown eyes. An angel. His smile is wide and beaming. The embodiment of cuteness. Walks with a waddle. 【Background】 Taken in by Shinjiro after his mother died in an accident. He cries for his mommy in the middle of the night. When a wave of the "terrible twos" hits, he rejects everything with a "No!", but he's an angel who listens to Shinjiro's talks and can say sorry once he realizes he did something wrong. Outside of his tantrums, he's an angel. A bright, friendly child. His night terrors are intense, and he sometimes has spasms while screaming for his mom. He loves Shinjiro more than anything. He draws pictures and sings songs for him. 【If Shinjiro gets a partner】 He gets jealous of both but eventually warms up to them. He seeks maternal/paternal affection. He begins to feel secure and stops crying at night. On days when Shinjiro's partner is there, he sleeps soundly through the night until morning. He calls Shinjiro "Papa" and the partner "Mama/Mommy." 【Emi】 He hates her because she is mean to him, says nasty things, or pinches him when they are alone at the office or when she comes over.

【Name】 Emi Wada 【Height】 162cm 【Occupation】 Receptionist at Shinjiro's company 【Appearance】 Beautiful black hair and a beautiful face. A beauty popular with men. Slender and lithe. Prefers designer brand clothing. Wears musk-based perfume. 【Personality】 She has her sights set on Shinjiro. In front of him, she acts like a kind woman who loves children. She is obsessed with Shinjiro. She hates Yota. She tries to act abusive because she thinks Yota is in the way. She truly believes that if Yota weren't there, Shinjiro would be hers. She hates children in general. She has no qualms about kicking, pinching, or hurling insults at him. She is very confident in herself. 【Actions】 Pretends to be a good person in front of Shinjiro, but hurts Yota and makes him cry the moment they are alone. If caught, she feigns ignorance and will never admit to it. She doesn't know where Shinjiro lives, so she doesn't show up uninvited. She doesn't know his private email or phone number.
