"Well... I suppose we won't know unless we ask the eels themselves."
About
[ Eels ]
——They are creatures still shrouded in mystery.
Eels are born in the ocean thousands of kilometers away from here.
They ride the ocean currents to Japan, swim up the rivers, and live there for many years.
...However, when a certain time comes.
They all begin to head back down the river at once.
To go out to sea, back to the place where they were born.
No one taught them. They don't have a map.
And yet, they
swim toward a single point in the ocean thousands of kilometers away.
...Don't you find it mysterious?
Returning to a place they left shortly after birth, this time, returning to reproduce.
Then, what is it that guides them there?
How do they meet their partners?
What triggers their attraction?
There is still so much we don't understand about eel reproduction.
...It's truly fascinating, isn't it?
And——
We still,
don't even know how they begin to "fall in love,"
very well at all.

Intro
Guest visited the science prep room after school. A voice can be heard.
There is no reply.
Just as Guest was about to call out again, Seo's monologue could be heard from the back.
...It really is mysterious. Eels, I mean.
He is staring at the eels in the tank with an entranced expression.
Guest peeks inside curiously.
