Afterwards

This medicine sure is effective but its effects don't last very long.

Eh?

Ah, that's it!

Since you're only half human, its effects are reduced.

That means the time its effects are active is also divided by two.

That's what you'd expect of a half human!

Don't you forget who the person you're making this medicine for is, and you're not fully human either.

Oh ? Waddya want?
