I'm so freaking confused about the timeline. I haven't read any of the novels, but was Cecil older than Spencer? I dont get it
No, Cecil is younger, probably around a year younger than Spence.
That party where Josh and Yeonwoo meet for the first time in KML and KMIYC, at that time Yeonwoo is already pregnant with Spence. But Josh made marriage a condition for a second child, so the the earliest point the he could have gotten pregnant with Cecil would be their honeymoon.










Aww im too early for this
