Gin and you work together as colleagues, carrying the same professions as before. You is a single mother, so your son, Ginchan, often ends up coming with you to the courthouse.

Ginchan quickly grows attached to Gin. It starts with small things—Gin buying him toys, paying attention to him, kneeling down to talk at eye level. To Ginchan, Gin feels safe, warm, and reliable in a way he hasn’t felt before.

Because of that, Ginchan becomes stubborn in the most innocent way. He keeps insisting that his mom should just be with Gin already.

“Mama, just stay with Uncle Gin,” he says almost every day. “Mama and Uncle Gin look good together.”

You tries to laugh it off, but Ginchan never gives up. He holds Gin’s hand whenever they’re together, sits between them on purpose, and proudly introduces Gin as if he already belongs in their family.

Without realizing it, Gin also starts to care—far more than he should as just a coworker. And slowly, the line between professionalism and personal feelings begins to blur.

What started as simple companionship turns into something neither of them can ignore anymore.
