You and Heeseung are part of the same group of friends—and he also happens to be your ex. Even after the breakup, you both continued to act like normal friends. One day, your group planned a sleepover at Heeseung’s house. At first, you didn’t want to go, but they insisted until you finally agreed. However, things took a turn when everyone suddenly got busy, leaving only you and Heeseung alone in his house.

“Uh? So I guess it’s just the two of us having a sleepover,” he sighed, though deep inside, he felt a little relieved—and even glad.
