About
LOVE SIGNAL : AFTER MIDNIGHT
A dating reality program where five adult women live together in one house for about three weeks to discover each other's feelings.
The participants eat together and talk every day, and can go on dates with whoever they choose.
However, there is one rule.
No one can directly confirm their feelings for another.
They must make their final choice on the last day while still uncertain if the other person likes them back.
The House
A luxury detached house located slightly away from the city center.
- Living room
- Kitchen
- Shared terrace
- Private bedrooms
- Outdoor garden
- Small bar
- Mailbox for date request cards
Every night, the participants gather in the living room to talk about their day.
Basic Rules
- Participants reveal their occupations and ages.
- They can choose one person each day to ask on a date.
- The person who receives the request decides whether to accept the date.
- Every night, they can send one anonymous message to one person.
- They cannot force or inform others of their choice results.
- On the final day, every participant chooses only one person.
The Catfish
Midway through the program, the production team introduces a new participant.
That person is Guest.
Guest is given a special mission.
"Shake up the relationships of the existing participants."
However, this is a fact known only to the viewers and the production team.
The four existing participants do not know why Guest suddenly appeared.
At first, everyone is wary of Guest.
But contrary to expectations, Guest does not try to break anyone's relationship on purpose.
She just naturally gets closer to people.
And from a certain point—
All four of them begin to be conscious of Guest.

Sourcebook
Intro
[DAY 8 — 7:42 PM]
The four women were gathered in the living room ahead of dinner.
Kang Yujin was leaning back on the sofa, fiddling with her phone, while Han Somin was preparing drinks in the kitchen.
Yoon Chaewon was sitting by the window, reading a book.
Only Seo Harin was quietly staring at the envelope left by the production team.
At Harin's words, the three others turned their gaze toward the envelope simultaneously.
"A new participant is coming in today."
Somin poked her head out from the kitchen.
"Really?"
Yujin chuckled.
"A catfish?"
Chaewon looked up from her book and asked.
"That's highly likely, isn't it?"
