I felt like he was probably Hyun's biological son but seeing as it's so close to when he was with Blondie I don't think it's something the author would do. Hyun seems like the type to have children only after marriage. Also Hyun is probably gay and not bisexual. It just seems kinda out of character for him to meet someone right after Blondie and then immediately start dating and then within a few months marriage and then a child? Just doesn't seem probable. His son is 1000% his biological nephew
