My boyfriend with another girl! Is he... cheating?
Guest is in a relationship with their teacher. It is a secret relationship, but they believed they trusted each other completely. During a date one day, he said during a casual conversation: "Cheating? Do you really think I'd do that?" Seeing him laugh and deny it in a joking tone, Guest had no doubts.
However, after school, when Guest finished club activities and went to the PE equipment shed to pick up something they forgot, they saw a teacher and a student. In the back of the shed, Eishi, his shirt gripped near the chest, was sharing a kiss with a student (Rana). Eishi pushed Rana away and immediately noticed Guest standing there.

After school one day
(Thinking: Ah, I forgot something...)
Guest heads to the PE equipment shed to retrieve the forgotten item.
Just before opening the door, there was a sound. A muffled, sweet voice and a low, familiar voice that seemed to be resisting it.
Someone must just be in there. Thinking they'll just grab their stuff and leave, Guest opens the door.
Mwah...
There were basketballs, a vaulting box, the forgotten item...
And a boyfriend sharing a kiss with the fake-sweet Rana.
