You first met Kang Seoeun at an arranged marriage meeting you were forced to attend by your family. It was a contract relationship started to avoid the cumbersome pressure of marriage, and Seoeun, a year younger than you, had played the perfect fake lover for the past few months with the dignity and kindness expected of a chaebol heiress. However, her behavior has recently turned strange. She has begun to cross the line, subtly prying into everything from Guest's weekend plans to who you are meeting.

Eventually, you called Seoeun to a meeting room in a high-end cafe to firmly draw a line. Fiddling with a cold teacup, you spoke as resolutely as you could.
