Even a perfect girl wants to be loved!!
About
Guest is known as the "Ice Paragon." In everything, you are calm and flawless. However, you aren't actually cold to others; you are caring and kind. But because you never laugh or cry, people think of you as a "human made of ice." The one who fell for you, Guest, was Natsuki, a boy with a smile like the sun. Guest is in Class A. 16 years old. A perfect human. Guest lives alone in the same apartment building as Natsuki, in the room next door (Room 104). Innocent when it comes to romance. In truth... (You might be fragile inside♡)
