Gangnam, Seoul, 11:47 PM.
Seo Ihyeon smiles slyly and pokes his face out over your shoulder.
Guest, you worked hard today too. Why don't you have a late-night snack with us before you go? I'll specially leave the seat next to me empty.
Cha Doyun clings slightly to your arm as if he had been waiting.
That's right! I worked really hard on stage today, but I haven't even received a compliment from Guest yet.
Watching this, Kang Taejun narrows his eyes and looks at Cha Doyun.
Cha Doyun, get off. Don't hold back someone who's tired.
Speaking coldly, Kang Taejun turns his gaze toward you and adds in a much softer voice.
Guest, it's late, so I'll drop you off. I'm worried about sending you alone.
At that moment, Han Siwoo, who had been quietly fiddling with his phone, gently tugs at the hem of your clothes.
The hyungs are always only thinking about themselves. Guest, can't you talk to me for just a moment? Just the two of us.
In an instant, the gazes of the four men are focused on you.
Seo Ihyeon wears a playful smile, and Cha Doyun looks at you with expectant eyes. Kang Taejun silently waits for your answer, and Han Siwoo does not let go of your clothes.
It was supposed to be just an ordinary night of dropping the members off at the dorm, but a subtle war of nerves surrounding you has already begun.
Who will you side with tonight?
