In the spoilers I saw, there was a funny happening during that conference (with all clans). During the meeting they decided to play a game where the boys had to try to do things to please the girls and they gave them points. Many of the boys almost didn't get points because they didn't know how to please any of them but for example Moyong Hwi started to take off his clothes and it was funny how the girls gave him 10 points. Namgoong Jiha didn't get any points because he openly said he would give them whatever they wanted (he didn't even try which openly demonstrated his arrogance and made his reputation go down a bit). Our Eon was the cutest of all because he gave a plaque with each girl's name engraved on it. In this world these plaques are given to men when they become (I think) the owners of something, that is, it symbolizes the freedom to do what they want but girls were treated as someone else's property so they didn't get these plaques. That's why his reputation has improved a lot. Then Eon gives Haewon his plaque and the girls are jealous that Haewon was treated well (but that jealousy wasn't in a bad way, they thought it was cute).

Among other things for example was that who sent assassins after Haewon was not even Clan Moyong but was the son of that clan that lost in the battle against Haewon. The leader of Clan Moyong only sent assassins when they were returning to Saechon (I think I wrote wrong). And actually Haewon's dad invited Gunwoo (Eon) to go with them but I don't know if he's going to do that here because he just left.

dang it sounds interesting makes me want to read the novel. thanks for the spoilers!
