Yes! I'm so curious of how the artist portray them cause in the novel it is said that Gyuwon is the least attractive of his family. To the point that they are afraid no one will find him attractive enough to date him. So when they met Hwayoung, they can't believe that he really likes Gyuwon and that he is brave enough to meet his family. Because surprise, surprise, Gyuwon's father is actually a pastor or the like and has a strong personality (you can guess why they have a falling-out). He also has female siblings, one of which Hwayoung thought could be his type if he is straight and not in love with Gyuwon (the one I'm curious about the most).
Honestly, I hate their thoughts about Gyuwon's looks and physique in the novel, and I sometimes question whether they really care about him ecen he became estranged from them. But Hwayoung has a good time showing them how he loooves Gyuwon as he is.

Is there any spoiler about Gyu's family in the novel?? I wanna know! XD
