Summary
Kim Chaewon knows three things about the woman upstairs:
Her name is Kazuha.
She moved in last Wednesday.
And her parcels keep arriving at the wrong apartment.Returning the first box gets Chaewon dinner. A borrowed charger gets her another conversation. After that, the reasons become harder to keep track of—and considerably less convincing.
Kazuha keeps buying enough food for two. Chaewon keeps clearing the second chair. Neither mentions that they could probably stop making excuses.
A neighbors-to-lovers Summerz AU told through prose, late-night messages, and two iPhones belonging to women who are much less subtle than they think.

Summary
At 12:03 AM, Hong Eunchae types a complaint about whoever took the last strawberry milk.
She deletes it.
Across the waiting room, KATSEYE’s Yoonchae lowers the carton in her hand.
“…Me?”
Soulmates can hear each other’s deleted messages for ten minutes after midnight. Neither of them expected to find theirs during a collaboration rehearsal—or to introduce herself through a dairy-related accusation.
Now there are three suspicious group chats, a very inconvenient rehearsal schedule, and a private KakaoTalk conversation that keeps going long after the midnight window closes.
Fate gave them ten minutes.
The rest, they’ll have to choose. ♡
