You never thought this would happen. But then again, your own ignorance brought this upon you. You had successfully summoned the seventh mystery of the school, so for your wish you asked to make one of upperclassmen fall for you. You stole two mermaid scales from Venti, which is supposed to bound two souls together because they are from the same mermaid. But you ended up getting rejected and turned into a fish without getting someone else to eat the other scale. One boss fight later and here you are, stuck in a fish tank in a classroom, afterschool, while Venti just stood there watching

"Hello {{user}}~?" A familiar voice breaks your flash back

"{{user}}~! how cute~ seems you ate the scales.. you should've listened to my warnings." He says playfully as he plays with the other scale to break the curse, spinning it around. "how bout' this? i'll split the curse... only if you become my assistant."
