Okay, so Teajun will find Yumin and after sometime they both will find out that they are shifters. Taejun won't react much since he already suspected it. Yumin's ears and tail will pop out during sex, taejun just says "So cute" And continues. Yumin thought it was a dream since his memories were hazy because of the green herb drug he gave him to help with pregnancy. He finds out that he still has his ears and tail while he was cuddling with taejun. But it's not the same for Yumin. He finds out that taejun is a shifter because his eyes look all crazy, like an apex predator, when he asks if he's a shifter too, he says yes and asks what animal he thinks he is. He says tiger, all scared. Then he remembers his family saying that he should stay away from tigers and Beom family and he gets even more scared. He thinks that Teajun pretended all along just to eat him. Taejun gets a call and from the conversation Yumin understands that Taejun drugged him, but doesn't know why. He takes his cat form and runs away. He manages to get away pretty far, gets injured, rescued by a college student and almost goes to a shelter because his cat form in human world is an endangered species. Taejun hires a "cat detective" to look for Yumin. From here its a long search, he will be slipping away from taejun. At this point, it's confirmed that he's pregnant. He has a dream where a baby cat (just like Yumin) and a baby tiger leaps into his arms, taejun knows he's pregnant but yumin doesn't know anything about his pregnancy. After a long search, taejun finds him and he still thinks that's Teajun's so obsessed with him cuz he wants to eat him. He's set to not reveal him hometown address because he is afraid taejun will eat his family too. Taejun is happy yumin is with him and he wants to clear all the misunderstanding that he doesn't want to eat him and he's carrying Taejun's babies. All while taejun is planning their wedding with his family. He's constantly having stomachache so he sneaks away (AGAIN) to go to a shifter doctor.
This is where I've stopped. I've skipped all the little details and just explained it briefly.
Haha I read the novel too. It drives me crazy that Taejun was not honest when he found him the first time. That could've stopped him from running again And poor Yumin still thinks he's gonna be eaten Damn, the misunderstandings are just... really dragging. And I believe the shifter doctor goes on to confirm that Yumin is pregnant with twins, but he doesn't believe him. Meanwhile, Taejun is planning some way to meet and win over Yumin's family.

So, I'm reading the novel and guyssss it's not looking good. Be ready for a shit ton of angst. You can ask me if you want any spoilers.
