Jeong Hyeok (Jae In's crazy ex) and Taeyoon are sibling! Taeyoon is the little kid and Jeong Hyeok is the high school student (at the end). Ohh hell no. What a plot twist. But I hope Taeyoon will not get involved in that family. Just live happily with Jae In and your child.
It like Navier telling Trashta that she always cares about her husband. Whether her ex-husband or current husband, Trashta will always act like Navier's husband was crazy over her when in fact Soveshit only married her because she's pregnant and Heinry hated her ass.
He did not... Oh hell no. Not out precious Yeomin will get his heart broken. Damn!!!!
