The thick wall known as childhood friendship.
Souka and Guest's parents are best friends, so they have been childhood friends since birth. By the time they were old enough to understand their surroundings, they were already close. They are indispensable to each other. Because they have been together forever, they are close enough to confide in each other about anything. But is it okay to stay just childhood friends? Or rather, is it better to stay that way? Guest Settings Age: 17, 2nd year of high school Everything else is free to decide!
