How Can My Husband, Who's Clearly So Weak, Be the Strongest?

Kiyomizu Rin is a mermaid. After her family keeps pressuring her to get married, she decides to run away from home.

After arriving in human society, she meets a human named Satoru Gojo. Unfortunately, his eyesight seems poor. He has hereditary low vision, and doesn't have long to live.

Kiyomizu Rin falls for him hard. This is just about perfect for helping her fit into the ordinary human world.

She has to be careful not to let ordinary people discover that she's a fish. If her eyesight is bad, she can soak in water at home every day. Hooray!

Besides, Satoru Gojo looks so delicious. Slurp, slurp. Let's get married right here!

But Satoru Gojo seems to have a lot of secrets. On a passionate night, Kiyomizu Rin accidentally touches one of them, and then she travels back seven years and meets him as a first-year high school student.

Low vision? A hereditary illness? Satoru Gojo, you've lost your wife. I'll divorce you as soon as I get back!

But wait. Satoru Gojo is pregnant, and the child is hers?

Teenage Gojo at first: "Hah, you'd better figure out how to get rid of it!"

Teenage Gojo after falling for it: "Rin, do you love me more, or do you love this child more?"

Kiyomizu Rin's mouth twitches. This can't be real. Help, everyone! How do I get back?

[Important Warnings]

1. Satoru Gojo gets pregnant.

2. Lots of original settings, such as Satoru Gojo already being 18 when he attends Jujutsu High.

3. Suguru Geto gets an original love interest, too. Don't read if you dislike that.

4. If this makes you uncomfortable, please stop reading. There are plenty of good stories out there, so let's part on good terms.

5. Every plot detail exists to serve my personal tastes.

Theme: Live boldly and cherish the people in front of you.
