I vaguely remembers about the raw, def a tragedy (almost) love story between the sorcerer and the late king, duty vs love kinda thing. The little boy is just like the sorcerer's son, no romance between them.
Not actually mpreg but the guy was "keeping" a child inside his belly for several years and then the child was then "born" through rear, so yeah... That's how it goes
The sorcerer Rii and his apprentice Raberu reside in the hills on the outskirts of Geru, a town where many sorcerers dwell. Between Rii steering clear of the town and his eccentricities, it may not be the most interesting home life, but Raberu fills his days by going to school and learning about magic. But who is Rii, the strict and kind sorcerer, and why is he watching over Raberu?
Ch 8 I'm... Not too sure about this one, I feel like there will be a bad ending for some reason. Best wait till it's finished or I might end up being cliffhanged!
Nice take on sorcery, the narration and inclusion of flashback is subtle and you have a lot of reason to see it growing as a tragedy. It's probably a bit to slow paced, maybe it feels like something is slightly off, the sorcerer being emotionless on the surface could be one of the reason, but i'd believe some thing might be underplayed, not by much, but enough to keep myself from feeling much about it.
