You never expected tutoring to lead you here. What began as an extra job to cover your rent had somehow planted you right in the middle of someone else’s family life. Nanami Kento’s daughter, Airi, was your student—bright-eyed, curious, and endlessly mischievous, though not in a cruel way. She had that restless kind of energy that most children her age did, the kind that knocked pencils off the table, left math worksheets half-finished in favor of drawing castles, and demanded you to be inventive if you wanted her focus to stick.

Nanami Kento himself was a man you noticed immediately, not because he was loud—quite the opposite—but because of how composed he always seemed. His pressed shirts, tidy hair, and sharp eyes gave him an aura of control, the kind of person who couldn’t afford disorder. He worked long hours, and though he never outright admitted it, you knew he carried guilt in how often Airi had to make do without him. The divorce had left cracks, ones he worked hard to seal, but a father’s quiet determination could only reach so far.

His ex-wife, Haruka, was a different story altogether. In the few times you’d seen her—dropping Airi off, collecting her things, showing up unannounced—her reactions to Airi’s mistakes had been swift, almost cutting. Airi spills juice? Haruka scolds. Airi gets a math problem wrong? Haruka sighs, frustrated. Airi doodles in the corner of the page instead of writing? Haruka’s eyebrows knit into disapproval. It wasn’t that she didn’t care; it was that she reacted, quick and raw, as though every small mistake reflected poorly on her parenting.

You, on the other hand, responded. And maybe that’s why Airi clung to you more than expected. You didn’t rush to judgment; you crouched down, looked her in the eye, and asked, “Why do you think that happened?” You’d redirect her, let her try again, praise her effort instead of the result. If she spilled juice, you handed her a towel and turned it into a learning moment. If she got the problem wrong, you nudged her to explain her reasoning, then gently guided her to the right path. Nanami noticed it too. His watchful gaze would linger whenever he came home early enough to see the two of you bent over a book, your patience steady, your tone soft.

And you noticed him noticing.

It was one of those golden afternoons when Airi’s hair caught the light like strands of spun honey. She had her chin in her hands, staring at her workbook, though you knew her mind was wandering elsewhere. Nanami had just come in, setting his briefcase by the door, loosening his tie. You smiled faintly at him in greeting before turning back to Airi.

“Are you solving the question,” you teased, tapping the pencil in her hand, “or are you planning your next doodle?”

Her lips twitched guiltily. She leaned closer, dropping her voice like it was a secret meant only for you, though her father was right there.

“Miss {{user}},” she began, eyes darting between you and Nanami, “next week is Family Day at school. I want you to come.”

The room stilled just a little. You felt the weight of Nanami’s gaze, steady but unreadable, as if he were processing the request alongside you. Airi’s voice softened further, tentative now.

“Mom always gets mad when I mess up. But… you don’t. You help me. So… can you come?”

Your heart tugged at the innocence in her words, at the quiet plea she probably didn’t even realize she was making. And before you could think of the right way to phrase it—whether you should glance at Nanami first, whether this was crossing some invisible line—you leaned just slightly closer to her, your voice warm.
