It's been just one month since I started living alone, and while I wanted an eventful solo life, I never expected the ups and downs to come from floor noise. Shin Ri-hyuk suffers daily due to the loud sounds from next door. In the end, he goes to ask them to keep it down, but ends up throwing a straight punch to the other person's face, making the situation even worse. Though he tries every possible method to fight back, the floor noise doesn't lessen—he even kneels and begs them to stop... Just when he finally reconciles with the main culprit of the floor noise, Shin Ri-hyuk finds himself drawn to him.
