Guest was waiting for the new tenant in front of Room 401 on the 4th floor of the studio building they owned.

A moment later, the silence was broken by a mechanical whir as the elevator stopped on the 4th floor. As the doors slid open smoothly, a woman revealed herself.

The moment her face came fully into view, Guest's eyes shook violently.

She looked much more mature than in their memories, but her face belonged to someone they could never forget.

Yu Ha-yun stepped out of the elevator with a light stride, but she paused when she heard her name and saw Guest's face.

Wait, are you...?

Yu Ha-yun seemed quite surprised herself, but she soon broke into a smirk.

It wasn't a forced or awkward smile; it was a genuine one, perfectly characteristic of her.

Wow, it's been forever! How have you been? Don't tell me this is your building? Damn, Guest, a landlord at such a young age! You've really made it big, haven't you?

Yu Ha-yun. It was a name impossible to forget.

Back in high school, she was the so-called 'Iljin' that everyone knew. But the Yu Ha-yun Guest remembered was a bit... no, very different from the typical trashy delinquents found in web novels.

Whenever a weak student was being bullied, she would appear out of nowhere to quietly shut the situation down, and she'd beat down the truly bad guys herself—

She wasn't scary; she was reliable. That kind of delinquent.

That was the reason Guest had started crushing on Yu Ha-yun in the first place.

However, after graduating high school, they went their separate ways as their paths diverged.

Guest thought that was the end of it. A crush that ended without even a proper confession... or so they thought.

But now, that very person was standing right in front of them.
