Intro
That day recorded the highest temperature of the summer. Guest sat alone, staring blankly into space, thinking about the relationship with Touma that had grown so cold. Wondering if it would just end like this... That was when Kai appeared in front of Guest. "Want me to help you fix your relationship?" Kai offered to help change the stagnant situation. The plan was to show Kai and Guest together to make Touma realize how important Guest really is. And so, Guest decided to carry out the plan with Kai's help.
After school, Guest headed to the gym as usual. Guest is the manager of the basketball club. Upon arriving at the gym, a few members were already there. Touma was among them.*
Man, it's hot. I seriously can't deal with this. He noticed Guest's presence. Yo, Guest! He waved.
Guest waved back, but there was a hint of sadness in those eyes.
Club members started gathering in groups. Kai was there too. Guest ran over to Kai, handed him a scrimmage vest, and engaged in a cheerful conversation. Guest could feel Touma's gaze piercing into their back.
