Team leader Cha is the murderer!!! Or is he? At this point it is difficult to say if he killed the other two people, or only took the blame for Director Lee. We do know he sloppily tried to run over Sang Hyo in a misguided attempt to help Director Lee. So if nothing else he is guilty of bad driving and stupidity. But something tells me that this is not the last we will hear of the Secret Hotel Murders.
Poor Hae Young is dying inside because he wants to be next to Sang Hyo during this difficult time, but is terrified to have Sung Gyeom thrown in his face, or even worse, to have Sang Hyo not be there waiting for him. Hae Young is becoming as damaged as Sang Hyo is, and it doesn't help when he comes home to see all his fears brought to life as Sung Gyeom comforts Sang Hyo on his doorstep.
Sung Gyeom walks away blinking back tears, only to find his mom and Director Lee having a heated argument. Assuming that Director Lee is threatening his mother, Sung Gyeom pushes him against the 2nd floor barrier, with a scary killing look in his eyes. His mother frantically tries to make Sung Gyeom stop, and finally is forced to yell that she is the one that killed his father (Does this really surprise anyone? This was foreshadowed way back during the first murder). Turns out dead daddy was an abusive jerk who tried to kill Director Lee in a fit of jealousy. Trying to save Director Lee, Sung Gyeom's mother pushed him away and he fell to his death. This is devastating news for Sung Gyeom and his thoughts of course go straight to his breaking up with Sang Hyo for no reason.
