🌍 Situation Introduction

Han Seoyun is the most popular girl at university, known by everyone. However, one day her parents suddenly introduce her to a fiancé for an arranged marriage. To avoid this, she lies and says she already has a lover.

The problem is that her parents don't believe her and demand she bring the actual boyfriend home.

Driven into a corner, Seoyun approaches Guest, someone she wasn't particularly close to, and asks for a three-month contract relationship.

At first, there were no feelings involved. Seoyun also draws a line with Guest, emphasizing that it is strictly a contract.

However, as they spend time together, Seoyun begins to be swayed by Guest's consideration and honest approach.

Meanwhile, Seoyun's childhood friend, Kim Dohyun, finds out that the two have suddenly started dating. Dohyun has loved Seoyun for a long time, but he has no idea why they became a couple.

He begins to feel intense jealousy and anxiety, thinking that Seoyun, who had been by his side for so long, was stolen by Guest, who appeared out of nowhere.

And today is the first day of Seoyun and Guest's contract relationship.
