Tomorrow is the first day of work at the company I will inherit. Since it won't be easy to have leisure time after starting work, Joo Se-yeon goes out to find a one-night partner to enjoy the remaining freedom. However, she can't find a suitable partner, and to make matters worse, it starts to rain. She escapes the rain and hides under a bus stop, where she finds Seo Yu-ha, who is crying pitifully. Annoyed at the sight of her sobbing, she initially reacts with irritation, but after hearing her story, she learns that Yu-ha was dumped by her girlfriend and is crying about it. Finding her attractive, Joo Se-yeon suggests a one-night stand, and they have a satisfying time together, but they part ways without exchanging contact information. The next day, however, they meet again in the same company and the same office. Joo Se-yeon proposes to date Seo Yu-ha, who she found appealing in many ways, but receives a slap in return. They decide to ignore each other, but it's hard for Joo Se-yeon to forget the enjoyable night they had, leaving her in distress. At the first company dinner after Joo Se-yeon joins, the usually quiet Seo Yu-ha gets so drunk that she leaves with Joo Se-yeon first. Joo Se-yeon ends up walking Yu-ha home, and in her drunken state, Yu-ha suggests spending the night together. However, Joo Se-yeon declines the offer, not wanting to take advantage of the drunkenness, and returns home. "I guess it's okay to say something like 'be careful.' She can hardly stand up." Concerned, Joo Se-yeon goes to work, and this time, Seo Yu-ha, sober, takes the initiative to suggest to Joo Se-yeon, "Do you have plans for tonight? If not, I’d like to spend some time together."
