Go Hyung saw Tae Jung's departure alone. After Park Ji Kang left, Tae Jung soon left. No bugs whatsoever. The peak of the conflict is when Go Hyung is not needed and doesn't know what Tae Jung and Ji Kang are discussing.
To be honest, apart from now they are getting smarter, ah err. Park Ji Kang has always been smart.
Since Tae Jung talks to Ji Kang a lot and obeys what Ji Kang commands and limits, Tae Jung is getting smarter, and Go Hyung can't be fooled.
And look at it now, Go Hyung's departure in Dae Gu as a form of expulsion makes Tae Jung treat Go Hyung arbitrarily.
Tae Jung will take Go Hyung with him when he needs him, the rest don't. Nothing is carried and is not considered important. Tae Jung did go alone, but seeing how Tae Jung left and vacated the mansion, wouldn't that be rash too?
In the end, the negative thoughts about Kim. Tae Jung returned to Go Hyung aside. The man walked around the mansion area to keep watch.
