4 hours for a monster? How weak!
He is no monster.... yes, he is strong, not aging, not getting sick, etc etc, but he is no monster, he is just a pitiful man.
The 4 hours is not because he is weak, it's because they agreed on the rules of Her working as a maid for 4 hours per day. When she is a maid for that 4 hours, she have to listen to the order of the Lord (him). Outside of those hours, he have to respect her as another noble family.
Actually, I meant it as a dirty joke (▰˘◡˘▰)
Yep, I did get yours dirty joke. Lol.
I think he will definitely okay doing more than 4 hours, but the girl won't be able to handle that.... hahaha
Hmm so night duties huh and she has to obey him for 4 hours ( ° ʖ °)
