I wrote my name on something that's important to me

Now, I can feel at ease at all times! Fufufu~

Eh? No, that's...

Come now, it's your turn next, Trainer-san

You also have something worth writing your name on, don't you?

That night

He properly wrote it on my palm, even while panicking... Fufufu...

I should wash if off before going to bed, but it's such a waste...

What do you think I should do?
