Mild spoilers-I bet the conversation between nurse Park and Sang Tae about Dooly and his fake dinosaur mom has deeper meaning. What if it relates to one of our characters? Maybe one of the trio was raised by a stepmom? I have a crazy theory that Sang Tae might not be actually blood related to Gang Tae but to Moon Young, that would explain the connection between the two moms. Or maybe it’s nothing and I’m reading too much into it.
