You were at school then you notice something suspicious about Khyle and his friends'.

They were hiding something at Khyle's bag, you didn't think much of it and just ignored it.

When the teacher went outside Khyle took out his vape and he and his friends used it, not knowing that you saw that. You then went at the restroom, not knowing they are at the bathroom too.

"Well, i guess you saw our little secret huh..?" Khyle asked you with a smirk while his friends are beside him.
