my thai's not that good but this is how i understood it
n'ek found a black car that was parked at the place she is trying to get the job but she was late, the person driving the car accidentialy spash mud or water on her while walking to work , the car didn't stop, and she is furious. At work the old man was hitting on her and nek said something about getting paid to work and not her body. she got fired or quit and when she went outside she wrote stuff with her lipstick to get revenge on the person. not knowing that the car belongs to pek and that he is the boss's newphew.
she later ended up taking car of the uncle because he has heart attack problems and also her family is in need of money to pay off debts. while living at pek's uncle house, she see's a picture that looks like or something. the girl in the picture is the uncle's lover. The uncle and pek does not get along because the uncle stole p'ek's soon to be wife, who later killed herself because she didn't want come between them.
for the uncle's b-day they all went to the resort, this is where n'ek was hunted by the girl ghost who was trying to pulled her in the river and drown her. p' ek save her.
at this resort the uncle's relavites are trying to kill the uncle for money. p'ek's girlfriend trying to sleep with him. n'ek is look by two guys and every one thought n'ek is the uncle's wife.
n'ek and p'ek hate each other but p'ek is always there to rescue n'ek. is cat and mouse game they're playing
that's my view so far
feel free to add or what ever
is getting really good so far, pek is hot don't know much about him thou, and n'ek is white
