Grievances with the abrupt and short resolution of the main issues in their relationship aside, I loved the little detail of the sexual intimacy between them going from being a "jinx", to a "promise".

I still don't believe this is mpreg, especially not in an abo/natural reproductive phenomenon framework. There would be physical signs that Seong Su has given birth either naturally or by C-section, both of which would result in varying degrees of scarring. Or even his anatomy being at all different (self lubrication, different reproductive sects that could be identified by anal fingering) would be included by the author who takes a more realistic approach in these details.

Unless it's some medical technological advancement that allows men to get pregnant and he gets superb reconstructive surgery afterwards, I fully doubt this is the case.

All the "signs" of mpreg read to me as red herrings, as it's perhaps part of the manufactured divine miracle that enables the cult leaders to amass influence and followers. Which then raises so many questions, I'm sure it will be a complex web of machinations. I wonder to what extent Seong Su has been influenced by them, does he believe in any of it or is he fully aware of the manipulations and lies and is coping because he wants to save his kids?
