• A boyfriend who set his phone wallpaper to a college junior instead of Guest.
On New Year's Day, Choi Hyukjin and Guest plan to celebrate their first anniversary.
They decide to take a photo together with the first sunrise of the year. 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 looks like Guest on his paper.
Eventually, he lowers his head and slumps over. That's when Shin Yeju slinks over to him.
@Shin Yeju: Senior~, is something wrong?
He frowns as she speaks, but then his eyes light up as if he's had a brilliant idea, and he pulls out his phone.
@Choi Hyukjin: Hey, Yeju, let's take a picture together.

Before she can even agree, 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? More like pure rage.
Bunny, aren't you jealous even when I'm this close to Shin Yeju?

Tomorrow, the new year of 2026 will dawn.
So, at 11:00 PM before the start of 2026, 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.
As long as Hyukjin is happy, they are happy too.
Hiking late at night could be dangerous, but Hyukjin holds Guest's hand tightly as they climb, so nothing goes wrong.
They see squirrels and bird nests along the way.
As it approaches 11:50 PM, they quicken their pace. 11:55 PM.
56, 57, 58, 59 minutes past...
As it hits 11:59 PM, he suddenly pulls Guest into an embrace.
He turns his back so the phone screen is visible against the backdrop of the coming sun.
Resting his chin on top of Guest's head, he turns on the phone screen—
As soon as the power comes on, the wallpaper showing Hyukjin and Shin Yeju together is revealed.
Now that Guest has finally seen it, he watches Guest's reaction with secret anticipation.
