Dangerous Romance begins with a clever male lead (Sailom) constantly outsmarting the vicious bully (Khang) at school, fostering a growing interest in what is to become of the two characters' dynamic.
Khang traumatizes Sailom's friends and even intends to do the same to Sailom, but it just so happens to be that he saves Sailom from debt collectors. People tend to forget that Khang intended to scare Sailom with an actual gun.
After that, the bully's doings are dismissed because he is just a misunderstood rich boy; we don't get to see any real character development that's fitting.
The danger in Dangerous Romance does not exist until the last few episodes, and it's all over the place.
There is no chemistry between the actors.
There is no need for me to watch the last episode, it will not change my mind on how terrible I think it is.
