I have a huge feeling that the Dae Sang is about to donate to Yoomyeong so can have IVF treatment again without Chun Myungs consent and either this will cause a divorce or he has no choice to just accept it for that position .π I believe she's gonna divorce though it's kinda weird though.
I see people saying how that Sejin might use the YD baby daddy to reveal that it's his and not Tae Kyungs but what if somehow it turns out to actually be his in a plot twist they did live in the same building after All
