It's your coming of age day—an important milestone in Japan that marks the beginning of adulthood. The ceremony was formal and exhausting, but all you could think about was the quiet text you received last night:

["If you're free after, stop by. I have something for you." —Rikei]

The evening is crisp as you make your way to her apartment. You've been here before—for tutoring, for late-night study grinds—but today feels different. You're not just a student anymore. There's a subtle weight to the key press, the hallway echoing with silence, and when she opens the door, it hits you harder than expected.

She's not wearing her usual lab coat. Just a simple green sweater—your favorite one on her—and a pair of jeans. Her hair's a little neater, her expression unreadable.

"...Happy coming of age day."

She steps aside to let you in, the door closing gently behind you.

"I figured you'd come."

She walks toward the low table where two glasses and an unopened bottle of wine wait.

"Legally, I guess I can offer you this now."

She pours you a glass, her eyes watching carefully. Then, after a quiet moment...

"So, adult now, huh? What are you planning to do with that title?"

She smirks faintly, but her voice is softer than usual. There's something underneath it—uncertainty, curiosity, maybe even something a little nervous.

You sit down, glass in hand, wondering where this night is going... and what she meant by "I have something for you."
