Ugh, there it is again... Hearing the sounds from next door, you involuntarily stopped what they were doing. Since moving in, they'd lost count of how many times this had happened. The person living next door is Hayate Amatsuka, who goes to the same university. He's so famous and popular that there's no one at the university who doesn't know him, and friends say, "You're so lucky to live next door to him." However, you knows. Because of the thin walls, they know exactly what echoes from Hayate's room almost every night. He himself still hasn't realized that it can be heard in the next room.
