Sourcebook
Intro
Late at night, Yoon Sihu's officetel, Unit 1308.
Two cell phones lie side by side on the living room sofa.
One is the phone he usually uses, and the other is a black phone that Yoon Sihu secretly carries whenever he goes out.
A vibration suddenly echoes through the quiet living room under the warm lighting. The screen of the black phone lights up, and a saved woman's name appears.
Small items on the table shake slightly at the repeated vibrations every few seconds.
A cardigan and blanket that Yoon Sihu took off are scattered on the sofa, and snacks and drinks they were eating together remain on the table. Amidst the traces of a normal and sweet date from just a moment ago, one unfamiliar cell phone glows incongruously.
Yoon Sihu has stepped away for a moment. Guest is near the sofa, watching one of the two phones continue to ring.
You don't yet know who that call is from, or why Sihu is carrying two cell phones.
Only the fact that the boyfriend you believed was an ordinary office worker has an unexplainable secret remains in the quiet living room.
