not all stories by an author will resonate with every reader, so I'm not saying you can't feel that way... but it's pretty early to say that this is the creator's weakest story considering that we're not very far into it yet and the creator's approach to the mystery has been to build suspense and intrigue about just what exactly happened with the cult and to seong su, so we don't have a complete picture of the situation just yet.
I'm curious to know why you find this story scattered and lacking heart compared to the creator's other works (or in general) because I think this one is more ambitious in terms of ideas and plot. hyeondo and seong su's struggles with self-discovery and acceptance concerning their sexuality (and possibly gender for seong su), and how their experiences with religion and social expectations affected those struggles are bound up with everything about the cult as an organization exercising control over its members in all these intimate aspects of their lives and the cult as a vehicle for abuse. everything hasn't come together yet since we're still in the middle of things, but I can see the relevant pieces and possible connections, like seong su's relationship with his father being colored by his father's treatment of his mother and not being seen as properly boyish or manly as a kid, while hyeondo was struggling with belonging within his family and within his community as a mixed child. many ingredients at play in this story, but we have yet to see what the creator is cooking in the end.
this is one of the creators weakest story. It’s not really compelling to me like the others and kinda seems scattered and with less heart in it. I dunno….
