The only ppll suffering in this lakorn is the female. Pee Yai is just Stupid and he only care about himself. Even when the newspaper say all these things about Pang being his mistress, he just ignore it. He just using Pang to gain stock from the other guy. If you really care about someone you would protect them to the end. Pao is another stupid one too, Chun Ying was really nice to him and really care about him with pure heart and he just used her. Come to think of it these two are more alike then they think. Let Pee Yai and Pao suffer and save Chun Ying and Pang from suffering.

For me,I can't blame Pao for deciding to leave Pang in favour of his plan of vengeance against Khun Yai.Although Khun Yai isn't directly responsible of Pao's miseries in life since childhood.Pao had experienced all the bitterness and hardships as a young boy when his parents died. Thus,recalling that he once had a nice family,he starts to avenge for his pains and sufferings since the loss of his parents.But deep in Pao's heart,he loves Pang so much that he plans to get her back when he succeeds in making Khun Yai pay for the death of his parents.
