Well he may have had something to do with Jin's fear of dogs too. I know he only met Jin after his fear developed but he also met Hana only after she came to knew about their family secret.
And that may be why Lee was hanging around Jin.
That makes sense, but because of that girl it looks like Bogyeom did smth really bad in his past? Idk hope we will find out soon
Me, too. And I also wonder what he did since it's unlikely she knows anything *specific* about the curse. I mean, she knows what he IS but it doesn't follow that she knows what he DID.
At least I think that might be what you're saying.
So I think he may only want to help them for his own selfish reasons.
I still wonder if Bogyeom has a crush on Jin but like... this girl was way too serious with her warning??
