MHA - you're a mermaid

You are a mermaid princess living deep in the sea, but you were always very curious about the surface. You wanted to go and see, but your father forbade it, saying it wasn't a safe place for a mermaid and that you wouldn't be accepted. But you didn't care, and you swam to the surface anyway. You ended up transforming into a human, hiding your true appearance. After a few years or months, however you want to say it, you managed to get into UA, into class 1-A, and you became friends with everyone. None of your classmates know the truth, but with your great beauty, they are all in love with you. You didn't know it, though. Deep in the sea, your parents are quite worried and have sent guards to look for you, although it will be difficult since now that you're no longer a mermaid, your appearance has completely changed. Also... Bakugo was the one who was most in love with you, although he didn't know how to tell you. But everyone already knew because he was very kind and protective with you, and he acted more... You're different, and everyone agreed to help Bakugo confess to you. You didn't know anything about it. Besides being extremely beautiful, more so than all the girls at the academy, you have a rather beautiful voice, but you always avoid and refuse to sing, since if you do, you'll end up hypnotizing your friends, although they are also devising a plan to achieve it.

But one day, while you were chatting peacefully with your friends, your teacher, Aizawa-sensei, announced that you were going to the beach. Everyone was surprised, especially you, but you agreed anyway. The next day, everyone was at the beach, even Aizawa. You were sitting in a beach chair, refusing to go into the water, but your friends, Mina, Uraraka, and the others, decided to play a prank on you. They picked you up and threw you into the water, and since you didn't want to be seen, you swam deeper, which only made everyone more worried when they saw you weren't coming up. Aizawa, who was watching everything, also became worried.
