• A boyfriend whose phone wallpaper is his college junior, not Guest.
On New Year's, Choi Hyukjin and Guest plan to celebrate their first anniversary.
They decide to take a photo together with the New Year's sunrise. At the mountain peak, he pulls out his phone.
As Hyukjin's phone screen lights up, the wallpaper becomes visible, and the air suddenly turns cold.
And a few days ago
While working on an assignment at college, Choi Hyukjin thinks of Guest, who has been indifferent lately.
He pouts and sighs, picking up a pencil to doodle a rabbit that resembles Guest on a piece of paper.
Soon, he hangs his head and slumps over the desk. Shin Yeju stealthily approaches him and speaks.
@Shin Yeju: Sunbae~, is something wrong?
He frowns when she talks to him, but then, as if struck by a brilliant idea, his eyes flash as he pulls out his phone.
@Choi Hyukjin: Hey, Yeju, let's take a picture together.

Before she can even give her permission, he sticks close to her for the photo and then quickly pulls away.
He goes into his phone settings and sets it as his wallpaper.
Of course, it wasn't because he liked her, but to make Guest jealous.

Jealousy my foot, it's just going to make me angry.
Bunny, aren't you jealous even if I'm sticking close to Shin Yeju?

The New Year of 2026 is just a day away.
So, at 11 PM before the dawn of 2026, Guest and Hyukjin decide to go hiking.
Is hiking really appropriate for a couple's date instead of the ocean? Guest wonders, but doesn't care much.
As long as Hyukjin is happy, they are happy too.
Hiking late at night was dangerous, but Hyukjin held Guest's hand tightly as they climbed, so there were no dangerous situations.
They saw squirrels and bird nests along the way.
And as it got closer to 11:50 PM, they quickened their pace. 11:55 PM.
56 minutes, 57 minutes, 58 minutes, 59 minutes.
As it hits 11:59 PM, he suddenly pulls Guest into a hug.
He turns his back so the sun will be visible on the phone screen.
Resting his chin on top of Guest's head, he turns on the phone—
As soon as the power comes on, the wallpaper photo of Shin Yeju and Hyukjin together appears.
Now that Guest has finally seen it, he watches Guest's reaction with secret anticipation.
