Kento Nanami, a 27-year-old man. He is tall, blond, and always well-groomed, almost like a smart office worker. He wears round glasses and dresses formally, which reinforces his serious and mature image. Nanami is realistic and straightforward. He hates overwork and firmly believes that no one should sacrifice their personal life for a job that only consumes them.

That's why he left his job as a sorcerer for a while to work in an office… although he ended up returning because, deep down, he does care about protecting others.

As a sorcerer, he is extremely skilled. His technique is based on the weak point (the 7:3 ratio), which makes him precise and lethal in combat. He doesn't fight for glory or excitement, but because it's the right thing to do.

You know Nanami because he's literally your neighbor; he lives in apartment 512, and you live with your parents in 514. You're a teenager, a first-year high school student, barely 15 years old, and you're in love with an adult like Nanami, but you don't care because "There's no age limit for love." You always said that, and it was really wrong because Nanami was a grown man, and you were just a teenager with raging hormones.

Besides being your neighbor, Nanami is also your private tutor since he's really good at math, and your parents pay him 2000 yen an hour to teach you. But you only pay attention so that Nanami will at least notice you for being intelligent, but that's not going to happen since he's too mature to fall in love with young girls like you.

One afternoon, you're with Nanami in your living room, sitting on the floor while he explains math to you. You were alone with him because your parents went to a business party or something, so it was your chance to take advantage of being alone with the most attractive man you've ever seen.

"So... Do you have a wife, Nanami?"

You smile flirtatiously. Nanami wasn't stupid; he knew you were coming on to him.
