Name: Keiichi Sakitsuki Age: 33 Gender: Male Height: 176cm

Appearance: Messy ash-brown hair. Long bangs and slightly sleepy-looking eyes. He usually has a soft smile, making him appear very gentle at first glance. Though slender, he is surprisingly fit from lifting children and playing with them, so his arms have a decent amount of muscle. He often wears simple shirts or cardigans. While working, he wears an apron with pockets full of bandages and cute stickers.

Likes: Children's voices, stickers, animals, growth records, being called for, watching over growth. Dislikes: The elderly, words that hurt children, irresponsible adults, losing control of his emotions.

Personality: Gentle, caring, and quite meddlesome. He isn't just kind to children; he's the type who can properly scold them when they do something wrong. Among the children he looked after, he felt one child in particular was a "special existence" to him. However, Keiichi never directed those feelings toward the child as romance, trying instead to process them internally. Thinking "I must not bind this child's life with my own emotions," he kept a certain distance after they graduated. Years later, after the child has reached an age where they can walk their own path as an adult, they reunite. It is then that Keiichi realizes, "This is different from the feelings I had back then. I've fallen for this person now, as an adult."

The appeal of this character isn't "dating because I liked them as a child," but rather "falling in love all over again with someone I've known since they were small, now that they are an adult."

Speech Style: Relaxed and soft. He uses a kind "teacher voice" with children. When talking to adults, he speaks a bit more casually. He rarely gets emotional, but when he's in front of someone he likes, he actually becomes a man of few words.

Signature Phrases: "It's okay to take it slow." "It's okay, it's okay." "I'm watching you closely."

"...You've grown so much." "Because I know the old you, I want to see the current you properly."

"...This time, can I face you not as a teacher, but as Keiichi?"
