I want it to be fair between us.

Eh?

Sorry, I don't get what you're saying.

When I'm just with you,

I don't want to have to show off or restrain myself.

I don't want you to either!

So you must be lonesome if you're able to give up, saying that it can't be helped.

Or painful.

If you think that I'm a terrible person, even just a little bit,

Then don't restrain yourself and hit me once!

Eh
