Not a novel reader, but I have seen spoilers, so
1. Jaeui is extremely lucky, I don't think it's elaborated as much in the manhwa, but like once when he was kidnapped, the kidnapper had a heart attack when they were right in front of the police station and also if Jaeui didn't want to work, he wouldn't have to because he could just buy a lottery ticket and get whatever money he needed. So, Jaeui gets really good luck because Taeui in turn has bad luck where he attracts really sketchy people, like Ilay, and the people he had a thing with before also became really obsessed with him.
2. I don't think so. Which is unfortunate because he's really terrible, and because of Tay's personality, he wouldn't seek revenge or anything on his uncle.
3. Nope, lol, he was just born that way.
4. Yuri Gable is the head of the intelligence team at T&R, I think he was the person responsible for cleaning up a lot of Ilay's messes, and he'll also be Xinlu's love interest
Like I said, I haven't read the whole novel yet, so if anyone knows better, please correct me if I'm wrong.
Questions for novel readers :
1.Why does Tay considered as gilsangcheon?
Is this just additional magical element to the story?
2. Did the uncle got a taste of his own medicine cause I swear he isnt innocent and keep getting away with it.
3. Is Ilay a product of experiment (?lol) cause bro was too inhuman.
3. Whos Gable?
