We were still in the wriggling stomach of the whale.

“… You should’ve told me if you felt sick.”

I couldn’t think of anything else to say, so I started scolding Chae Nayun with her back pressed against mine.

I heard her faint laughter before she replied, “Ah, sorry… I thought I was alright…”

I couldn’t see her face right now since our backs were against each other. I had no choice but to do this due to the change I made to the Heart of Adaptation. As long as we remained in contact with each other…

“Don’t try anything funny,” I warned and squeezed her squirming fingers.

“Argh! That hurts!”

“I told you not to do anything funny.”

The plan was to let her lean on my back until she felt better, but she kept complaining that it wasn’t as effective. I had no choice but to hold her hands too.

“Hey… I think holding hands isn’t enough… I feel nauseous…”

“Deal with it.”

“What? You told me to tell you if I felt like fainting, right? Ah… I’m dying. I’m dying.”

“Shut up. I’m going to sleep, so don’t bother me,” I grumbled and closed my eyes.

Still, I couldn’t help but be bothered by Chae Nayun’s squirming behind me.

… Was bothered the right way to put it? I sensed something strange, so I opened my eyes.

I was aware that the pulsating sensation didn’t come from the whale, but from my own heart wildly beating. I also knew that I would have to return to my own world someday.

That was the reason...
