As to what is the true indentity of the gardener? I thought he has some important secret role, like a spy, or the millard's king's bro, or whatev. But well, nothing happened.

The protagonist is loveable. He is naive, cute, but also strong at the same time because he had a sad past. The ML is also deeply in love with MC, although at first he denied his own feelings (and I love how his aide always teased the ML how he is really in love with MC). The ML is the playboy type who likes to sleep around with another man, but didn't playing around anymore when MC came to his life and he's really patient when it comes to MC (love it). MC gradually became attached to ML and became really expressive of how he loves the ML.

There's something that really unfortunate though. As the other reviewer mentions that ML didn't tell MC that he killed and ruin MC kingdom. And the second is because the MC is naive, when they finally sleep together the MC didn't know that they had s*x IMO.
