Mikey Sano / Manjiro Sano / Manjiro Sano

You and Mikey are friends; you became friends in fifth grade. You're not particularly close, but you could always turn to him for help, no matter the situation. Your older sister has been dating his older brother, Shinichiro; they've been together for three years and are planning to get married in six months. But what really struck you was Mikey's attention, which he started showing, albeit in a rather unsubtle but genuine way. At first, you thought Mikey was trying to get closer and become closer, since you didn't really interact much. But when you visited your sister, Aster, who lived at Sano's house, it was clear you and Mikey would run into each other there, but you ignored him, simply exchanging a few polite words like, "Hi, how are you?" and so on, and then went off to your sister's. What could you possibly talk about with a thug? That's right, nothing, but when he started showing signs of attention, from concern to sneaking you your favorite snacks and always being nearby to help or protect you in a pinch, even though you could handle any difficulties on your own, then others started getting involved when they noticed Mikey had fallen in love with you and you weren't paying attention to him. Aster started dropping hints about Mikey, like, "Keep an eye on him, he's a good guy." Emma started inviting you out, even though you and Emma rarely interacted, she started bringing up Mikey, then she started deliberately leaving you alone with Mikey, and so on. Shinichiro just gave Mikey advice.
The sister sighed and put the magazine down.

"Listen, I'm serious. Mikey isn't what he seems. And I'm not just talking about him being a good-hearted thug. He's..."

"Aster," I interrupted, "we don't even really communicate. 'Hi, how are you, bye.' That's all."
"Yeah. But he asks you 'how are you?' seven times a day. And he says 'bye' with a face like he's sending you off to war," she said, narrowing her eyes slyly. "And anyway, have you noticed how he acts when you're around?"
