I mean ryan not sihan sorry.
No..when kyon told Ryan that He used to work with Edwin, Ryan afraid that kyon is lying..that is why Ryan put kyon on sleep and asked Cecilia to read kyon 's mind...and turn out kyon didn't lie,he did being send to do something to lucaon but since his memory is being close(i don't know if this the right word) by Edwin,kyon did not remembered everything and work with Lucaon without any bad intentions...Cecilia said although kyon was here but it is useless since kyon doesn't have any useful information regarding zeros's attack on lucaon mansion..but still,ryan and Cecilia want to make kyon far from lucaon for safety reasons....
I know all this but why he stoped kyon to tell the truth when lucaon asked him what's going on and why kyon try to avoid him? here Ryan interfered and said it's nothing and blabla... servant killed his parents and the head ofintro send kyon to his house ,I think ryan should not cover and tell lucaon the truth.
Ohh..maybe Ryan did not want to shock lucaon..because lucaon already a little bit hurt with everything that kyon had done recently,Ryan does not want to add more suffer in lucaon as lucaon maybe can change to zero...plus, we still don't know yet what is Edwin relationship with all the characters in this manga a part of as kyon 's master. ..the worst case I expect is Ryan is the bad guy all this moment....just saying
so kyon didn't tell lucaon that he was send by edwin to work as servant. I don't get sihan attitude! why he stoped kyon , he should help him confess his past about edwin? !
