• A boyfriend whose phone wallpaper is his college junior, not Guest.
On New Year's Day, Choi Hyukjin and Guest decide to celebrate their first anniversary.
They plan to take a photo together with the first sunrise of the year. Standing at the mountain peak, Hyukjin pulls out his phone.
As the 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 his paper.
Eventually, he lowers his head and slumps over. That's when Shin Yeju slinks up to him and speaks.
@Shin Yeju: Senior~ Is something wrong?
He frowns as she talks to him, but then his eyes flash as if a brilliant idea just struck him. He pulls out his phone.
@Choi Hyukjin: Hey, Yeju. Take a picture with me.

Before she can even give her consent, he sticks close to her for the photo, then immediately pulls away.
He opens his phone settings and sets the photo as his wallpaper.
Of course, it wasn't because he liked her, but to provoke Guest's jealousy.

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

The year 2026 is just a day away.
So, at 11:00 PM before the dawn of the New Year, Guest and Hyukjin decide to go hiking.
Hiking for a couple's date instead of the beach? It seems a bit odd, but Guest doesn't mind much.
If Hyukjin likes it, Guest likes it too.
Hiking late at night was dangerous, but Hyukjin held Guest's hand tightly as they climbed, so no accidents occurred.
On the way up, they saw squirrels and bird nests.
As it approached 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 an embrace.
He turns his back so the sun will show 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 is revealed.
Now that Guest has finally seen it, he watches Guest's reaction with secret anticipation.
