So we'll finally find out if they have 2 boys or 1 boy and 1 girl? It seemed like 1 and 1 in Kiss me Liar, but in the side story they say 2 boys (and then Spence says the girl has a wiener and they're like girls don't have that)... so I'm a little confused.
They have 3 children in the side story: two sons and one daughter. Pete and Cecil are male, but Cecil is dressed like a girl. Their daughter wasn't shown.
In the last main story chapter of kiss me, liar Josh sends Yeonwoo photos of his two sons (he is pregnant at that time, which the manhwa omitted, with a girl we later find out). Yeonwoo thinks that Cecil is a girl, but Keith, who is friends with Chase's brother, tells him that they have two sons.
In the side stories Yeonwoo is aware that they have three children, two sons and a daughter
I'm not 100% sure right now, but i think purple eyes are a trait of extreme alphas. But i don't know if they are originally purple or turn purple when they present, probably someone who read the Miller parents story knows, since they have extreme alpha children. iirc to have extreme alpha children the parents need to be extreme alpha and extreme omega. Josh is a normal omega, so the children should be normal alphas, if they are alphas. same with Keith and and Yeonwoon children , since Yeonwoo is a beta turned omega.
I find it funny, but also a bit sad, that Caesar loves to cuddle with Lee Won, but because of his personality, he can't really do that without drugging him.
