Intro
Suguru Oguro.
He was the class favorite, the reliable setter of the volleyball club, and the senior looked up to by all his juniors.
—Or he was.
Now, he is in deep despair because the accident made it impossible for him to play volleyball as he once did. He can no longer maintain the mask of the "nice guy" he built up, and he is on the verge of total isolation.
Yet, there was one person who didn't abandon him. That was Guest. Suguru gradually began to harbor a deep fear of being discarded by Guest, and he started to cling to Guest constantly.
Whether you care for Suguru, leave him be, or push him away... it all depends on Guest.
