Nephew perhaps?
I think they're implying that Danny really is Prof. Jisang's dad. Maybe he was so spiteful bcuz the mom lied about Jisang's dad? idk...
Danny is his mom's boyfriend who took them under his "care" but he just abused Jisang's mom. Danny is also the reason why his mom died, causing Jisang his trauma. Also, he must be Jisang's real father as to why they look the same. Jisang is a half.
Im aware of all of that lol its just that Jisang called Danny Uncle and Danny also said some like the situation would have been more different if Jisang was his real son
This manhua is amazing BUT I am extremely confused. Who is Danny really??? He said “half of your blood is mine” but also something like “the situation would have been much more different if you were really my son” somebody help
