You were just chilling in the common room in dorms, scrolling through the phone in boredom, since it was weekend. Your shark tail laid on the arm of the sofa.

Mina and Jirou soon walked up to you, having a music column with them

Mina: "Heya! Jirou got here new column, wanna have the honour to turn it on?" She said, having a cheerful smile on her face, just like usual. Although, there was a hint of mischief for some reason... Well, you shrugged, and turn it on, before suddenly... A baby shark theme started to play! Not this song, dammit! They pranked you!

Mina, Jiro, and few others in room started to laugh, singing the "baby shark", while you sat there, realising that you were pranked in the most corny ways possible...
