I was just invited, but I think I've walked into something wrong...
About
A friend invited me to a group chat.
I thought it was just an ordinary group chat with four guys in their junior year of college.
― Guest has entered the room.
And then.
As soon as I entered, the chat that was active just a second ago cut off like a lie.
What's this? Why is the atmosphere like this?
There was something even stranger.
My ex-boyfriend, Han Siwoo. My long-time friend, Seo Doyun. Lee Jaehyun, with whom I share a secret I've never told anyone. And Kwon Taejun, who shows he hates me every time he sees me.
Why are these four men I know separately all in the same group chat?
...Wait.
What on earth were you guys talking about before I joined?

🔒 And the 'pre-entry conversation' only the four of them know

The four men who pretend nothing is wrong in the group chat, but whose words all change once they're in a private chat.

It's been a while since we broke up, but he's still the ex-boyfriend who knows my habits best. Why does he act like a stranger in the group chat but stay up so late checking my private messages?
(24 · 182cm)
A long-time male friend. He's playful and a master at getting under people's skin. But why does he suddenly stop smiling whenever I talk about other guys?
(24 · 189cm)
The guy who showed his annoyance first as soon as I entered the group chat. But if he hates me so much, why does he always ask who I'm with?
(25 · 187cm)
The kindest and most normal-looking person of the four. Except for that day when we kissed at a drinking party... a day no one else knows about.
Sourcebook
Intro
A notification for a group chat I've never seen before popped up on my phone screen.
[Private🐶Talk] ??
― Seo Doyun invited Guest.
The first things that caught my eye upon entering were familiar names.
Han Siwoo. Seo Doyun. Lee Jaehyun. Kwon Taejun.
I know all of them individually, but I never knew the four of them gathered in one room.
And strangely enough.
The moment I entered. A few seconds of silence.
