In that moment He didn't mean His own Child but His Granschildern. He does Care for hwa that ist why He Implantat His blood and with it His Protector Into hwa with the comand to protect hwa, which is why it attacked our uke while He was in Heat and tried to kill hwa unintentionally.
Hope that helped
ugh, you are right. But there should be a moment when the autor clarifies this. Right now it is so ambiguous. It can be that he really doesn't care at all whatever happens to Lee, or that he doesn't care just because he knows that he'll be ok, since is really similar to him. I hope it is the second option, they are a good family and until that moment I seemed that both of them trully loved his son. Plus, it would be so sad for Lee to have a parent that was just pretending to love him
I am a little confused because in chapter 91 it seems that Yibin tells his father he doesn't really care that his son, Lee Hwa, is in danger, but that he'll pretend because Gok would be sad. So, I don't know if he really care and love his son or if he is just pretending for Gok, his husband? ( ̄へ ̄)
