Thank you Also I have more here Tbh I have an easy about what I understand about this story but Manga.go always cut my comments so yah, I'm uploading it little by little.
• Lord Baeksa has a trauma when it comes to being alone bc of his past experiences getting locked up.
•Yehwa is (ML) stepfather (By the contract made between him and Jihyo). He has a crush with Jihyo (ML's mom).
•As we see in the flashback, I mean the first appearance of Jihyo, she said it's not good falling for someone like Yehwa (maybe bc he work as whore, and nothing good will happen liking someone like him, as she talked with kid ML). But then there's also another flashback that show's she's blushing and grinning passionately with Yehwa, so now this is where it's confusing. If she reciprocated Yehwa's love or she's just playing/pretending loving Yehwa for the money Ig.
Btw this is just what I noticed, it's not yet confirmed if she fall in love or not. Also we don't know where she is right now, if she's dead and if yes how did she die? What was Yehwa's reaction about it. And if she is alive, where is she, did she know that Yehwa's body was used by Lord Baeksa, or did she have a method communicating with her son(ML).
1.The first one is that there are two demi-drakes. White-drake which is Lord Baeksa and Black-drake which is Sahyeon (tho they are inhabiting both bodies). 2. In the flash back it shows that the other half of Lord Baeksa soul is within Sahyeon body. With red eyes, fangs and all (shows that isn't a human). 3. Lord Baeksa is not aware about Black-drake existence or I guess the identity. 4. Black-drake is missing w/o a trace. We don't know if he's still alive or just hiding. 5. Heon hated Sahyeon's younger brother bc he thinks the younger brother should be the one to have Black-drake within him. Bc as I said he like Sahyeon, ig he didn't want Sahyeon to be dead. 6. Younger brother of Sahyeon had died by the doing of Black-drake (Sahyeon). He was killed but came back alive possessing another body of a young master who is frail and in sickbed. He's the one who send the letter to Heon about Sahyeon, in the letter it stated Sahyeon has perish. 7. Yehwa hated ML bc he's stealing some of his time that can be spend with Jihyo (ML mother the one Yehwa has feeling for). This shows why he hated ML in some flashback if you read thoroughly tho this is not the only reason why.
8. Some of ML comrades (when he was a guard/officer) raped Yehwa his stepfather. And I think as they we're raping Yehwa, maybe they mocked him and told Yehwa that ML is earning money to spend a time with him (which I guess can be understood as ML want to have sex and do what the other customers do to him too). Btw this is misinformation on the part of ML comrades bc ML earned money to grant freedom to his father, so that he won't work as a whore anymore. The point is ML wanted to buy Yehwa's freedom but misunderstood by his comrades bc they think ML just wanted to buy his stepfather to have him to himself which make it look like to the eyes of the others he desired his stepfather's body more than anyone. 9. Lord Baeksa is possessive when it comes to Hong and Muhyeon (ML). Bc for him, they were his possession, for him alone. Tho it also shows that he wanted Muhyeon to also shows the same affection ML had towards his stepfather to himself (Bruh I dunno if you understand this one). But yah Lord Baeksa is sensitive about Muhyeon feelings. He's easily brothered when it comes to Muhyeon . 10. News flash Muhyeon didn't like Heon (gray hair young master). He's jealous(?) when Lord Baeksa address Heon with his first name (he stated that why Lord Baeksa saying Heon's name tenderly and softly but when it comes to him he was called and annoyed. can't help but laugh. Anyway he's vexed when it comes to Heon's presence.
