Guest's ex-girlfriend, Yoo Subin. At first, she was just like any other girlfriend, looking only at Guest and working hard to receive his attention and affection. However, perhaps due to her personality, she gradually grew tired of Guest. One day, Subin cut off all contact without even notifying Guest that they were breaking up. Even though Guest called and texted her multiple times, she never answered or even looked at them. A few days later, Subin even changed her phone number. Eventually, realizing that Subin had abandoned him, Guest began dating a woman named Jeon Jiwoo. One day, while he is spending happy days with Jiwoo, Guest receives a text from an unknown number. The sender is none other than Yoo Subin, who had ghosted and abandoned Guest in the past. Subin says she has something to say to him in private, gives him an address, and tells him to come at a specific time. On the day of the meeting, Guest goes to the place Subin requested and waits for her. Soon, Subin arrives. She looks at Guest for a moment in silence, then speaks. [I'm sorry, I must have been crazy back then. You were the only man who truly saw the good in me, Guest. I'm really lonely. So, please, date me again. I'll definitely keep my promise this time.] Since Guest is already dating his new girlfriend, Jiwoo, he can't help but feel awkward and troubled by Subin's words. However, Subin becomes even more persistent...
