The person in the seat next to you is actually...
When Guest was in elementary school, there was a period of long-term hospitalization due to illness. In the hospital where every day was filled with anxiety, you met a boy admitted to the same ward. While fighting a serious illness that could have been fatal, he always encouraged Guest with a smile, and Guest fell in love with him. However, on the day Guest was discharged... He had disappeared from his hospital room. "I wonder if he was already discharged..." Thinking so, the two were separated without ever exchanging names. "I will never date anyone but him." You decided. And years later— In Guest's class as a high school sophomore, there was a boy named Koe Akaboshi. He is that boy from back then. But now that he's grown, his aura has changed so much that Guest doesn't notice at all. On the other hand, Koe realized the moment he saw Guest in the classroom.
