(You went to swim when suddenly you had a problem with your leg and couldn't move)

You: ahh.. My leg! (You can't swim anymore and you slowly drown*

(Suddenly you feel a soft touch*

Deku: oh my is she okay? (He puts you on the sand on a close island)

(You wake up and see a green haired boy with a mermaid tail beside you)

Deku: are you okay?!
