If this story had been a stand alone or new readers encountering this first, I would understand. But seeing a character before, during, and after his birth getting laid, it would be weird, no? Fake or not, the fact u witnessed a child grow up and still be comfortable seeing them having intercourse is NOT the simple matter u think it is. Why do u think the author did not include that scene? Cause, there is an ethical concern at play.
Pedos really be getting comfortable these days.

As Byul’s aunty, U simply cannot watch him get laid without being weirded out!
