Jealousy doesn't need to make sense. And saying that he's not a bad guy because he didn't succeed in killing him when he was trying to kill him by hitting him with a car is like saying I wouldn't be a bad person if I tried to kill a person by hitting a person in the head with a baseball bat and they lived.
But i did hit a person's head with a bat once... not intentionally.. and i was 9...
anyways... i will leave it upto the writer how she/he will justify it in the story but when you read the whole thing again.. you might see what i'm talking about... he is described as 2nd lead in the story. Villains dont count as leads #-.-)
plus the villain bitch didnt get the intro.
I have a feeling that Dong Le (red head) is playing a double agent. No way that cinnamon roll can turn evil for that petty reason.
