I already told you to stop biting me, Yukio!
Even if the would heals quickly, it still hurts, you know!
I just unconsciously.
Who would have known that you have a habit of biting people?
I don't think I have that habit.
When I start feeling Nii-san's skin smell of your sweat.
i start thinking things like 'This isn't enough.'
That old man...
He said that by mixing our blood together, a great power will be born.
