I didn't care about the brother and his love interest's story (dojin and taeju).
I felt like their dynamic was almost exactly like dowon and beom's. It doesn't help that dojin looks exactly like dowon but with slicked back hair and he used his resources to help taeju just like dowon did to beom. It kind of felt like reading dowon and beom's story all over again. Only difference was their careers with dojin being a sketchy lawyer instead of an author and taeju was being screwed over by his brother and a cult instead of a weird obsessed CEO(?). (Also, same face syndrome's gotta run in the family. Cause their mom also looks exactly like her sons but with some wrinkles and a wig lol)
Taeju was another black haired, big tiddy bottom with money issues just like beom was until dojin/dowon helped them, respectively. Beom and Taeju also had no choice but drop their dreams in order to try and make money other ways. Dojin and Dowon are also really obsessed with their partners in almost the exact same way which just felt really uncreative. Could have made dojin have a submissive top or idk just something different that way he doesn't look and act almost exactly like his bro.
Anyways, I'm just glad to see dowon and beom again lol. (=・ω・=) I live for dowon being stupid and horny.
Yeah yeah yeah I get that he's a dragon and he's technically ageless or whatever. But since his first form was of a child, he acts like a child, he's seemingly going through adolescence like a normal human (or maybe faster. idk i cant tell how much time has passed) and acting like a jealous teenager. If it looks like a child and acts like a child but "hyo-un's not human so it doesn't count." It's giving the same energy as "b-but the loli is 1000 years old!!"
Ofc I don't think taehyuk's intention is to groom him, but I do find it sketchy that he's basically raising hyo-un as a guardian/parental figure and he will later develop a romantic/sexual relationship when hyo-un's takes on an adult appearance. It's like the usagi drop manga all over again.
