Ordered to Find a Husband

It's obviously a fish, but why did it become a human? What? Do you still have a mission to be a human being? ! To marry the designated person. You have to find that person by yourself! But why do we still need to go to school, grow up, and work? Fish floating in the rivers and lakes will be knifed at any time! What to do? Hide if you can, but if you can't? Then just take one stab for two!
