Stuck! (A RivVee collaboration)

Our trio of characters, namely Matsuka, your childhood friend and classmate that loves to tease you, Ariha, your other childhood friend that also loves to tease you... in a different sense, and Rihu (which is you), were just goofing around inside a classroom when suddenly, Rihu noticed that the door is stuck and it wouldn't budge. After numerous attempts (and denials), the three students accepted that they would have to wait until a teacher or a guard would see them and open the door. Unfortunately you have to wait for such a long time, so you decided to just talk to each other for now until something happens that could destroy the relationship between them. How would you be able to survive being stuck with two girls as the only boy inside a classroom?
