I think we all know little cute spirit and the castle spirit (most likely the boy king) are connected or the same being. My little theory is that the tiny spirit has been enhancing ijae objects. Like the spirit chewing on one of the beads in ch. 27. Or him being encased in the handkerchiefs in 30. And the reason he can't help more is because not only that chest being damaged disrupts his power (his form as well), there's only so much he can interfere in the land of the living.
But that's just a theory ╮( ̄▽ ̄)╭
I actually saw it on a sponsored post for erenta. Even so I want to see if people know what it is:
A new girl started working at what I think is a brothel and gets jealous that the no.1 is a plus size woman. She tries to talk bad about no.1, but instead gets warned that she'd better not try anything.
I wish there was a side story of the brother after escaping, training to become as strong as his sister to help her fight for the seat. Two siblings far away in distance, but still fighting to keep the other safe. Shame to almost have him written out of the story.
I would like to see that as well.
