You decided to take Tohru and Kanna to the beach because you wanted them to start learning more about humanity. That and you felt Tohru should get a break.

(Y/N): Okay, here we are.

Tohru and Kanna: YAY!/Yay.

(Y/N): (blushing) Wow Tohru, you look really cute in that swimsuit.

Tohru: (blushing) Thank you (Y/N). Do you want to-

(Y/N): Not in a public place.

Tohru: (pouting) Aww. Say, why are there so many people out there in the shallow end?

(Y/N): Because it's dangerous.

Tohru: Oh, I see. Leviathans are very dangerous.

(Y/N): No, not that. It's because of drowning.

Tohru: Humans can't breathe underwater?

(Y/N): Not many can.

Tohru: Heh, primitive.

(Y/N): And you?

Tohru: Of course. It feels nicely to swim too! Hmm ...

She got out a tube of sunscreen.

Tohru: Can I apply some sunscreen to your back, (Y/N)?

She had a pervy smile, and a bloody nose.

(Y/N): Already put it on.

Tohru: OH COME ON!

You then saw a beach house nearby.

(Y/N): (Sigh)

Tohru: What?

(Y/N): I remember coming to this beach with my parents when I was really small. That beach house has been there for a while now.

Tohru: Your parents?

(Y/N): Tohru, how are your parents like?

Tohru: Well...

She remembered her father.

Tohru: Respectable.

On the side, Kanna saw a crab and grabbed and ate it.

Torhu: What about yours?

(Y/N): They died when I was really young.

Tohru: Oh.

(Y/N): Yeah, but we had a good life back then. I miss them.

Tohru: Is that why (Y/N) is able to relate to me? Seeing someone alone, he knew how it felt? Because he was like that. Can humans really learn to live with dragons?

(Y/N): Tohru?

Tohru: Yeah?

(Y/N): Can I ride on your back?

Tohru: Wh-What?!

Soon...

You and Kanna were fishing on Tohru's back, while she was in her dragon form.

Tohru: Ah, it feels so nice. The water isn't hot, and the salt feels good for my scales!

(Y/N): Heh, I'm glad you enjoy it.

Kanna managed to catch a big fish.

(Y/N): Good job Kanna!

Kanna: Yay.

She ate half of it.

(Y/N): My, you've got a big appetite!
