Wait i'm confused rn. Can somebody pls explain what is going on?

Well, 57 starts with Lan (redhead ML's older brother) blackmailing a corrupt officer to help him "catch" fourth Prince (the one behind MC getting drugged and kidnapped), who is helping the officer steal money. It is heavily implied, that the crown Prince (the kid) is fighting against corruption and will harshly punish corrupt people.
Then, there is a flashback to five years ago, where Lan arrives at residence where he was appointed to govern over the local territory. He was given the title of prince of second rank by his majesty (I think, the current emperor? If I remember correctly, Lan and ML are the crown prince's cousins), basically he was aknowledged as someone close to the royal family, but not a descendant who could inherit, as far as I know. There, some kind of servant basically says that Lan's father left him with a task for Lan to do. I think, these two scenes are related (as is the discussion about the father in chapter 58), and what I can see, is that the father was investigating the fourth Prince and his mother, and left Lan with the task of continueing that. Whatever he found, he got killed for it by the fourth Prince and his mother.
Next is the bait scene, the massage. Nothing important happens, I guess it's just there to show that MC and ML get along well.
In chapter 58 the bait scene continues, before MC finds some kind of important document.
Next, we can see the assasin's master and his other disciple, and they talk about how the blue haired guy protected ML from fourth prince's henchmen, and Blonde is not happy that Blue got involved with politics, and wants him to quit. Blue refuses, since his student is friends with MC and will be involved anyway, so Blue wants to protect him. He also makes a comment, that Blonde was the one who got involved first, out of the two of them. Then, Blue asks what Blonde found out in his investigation, and he says that ML has been secretly trying to find evidence and witnesses to his father's death so that he can get the case reopened. MC is shown next with the document in his hands, so it's probably something to do with the father's case.
The preview doesn't show anything important.
If you got any questions, I will try to answer to my best ability.
