I honestly think that Som shouldnt view Chit so negatively. There was a scene in ep 3 when Som trying to show off her brand-named purse to Chit, and Chit reminded her that she shouldnt depend on material items or wealth to bring her happiness, because it wont last long. And there are times where Chit constantly reminding Wee that he should go back to his fiancee and that she's waiting for him. Chit even told Wee that he should reflect his action because having a mistress hurts his fiancee the most. I think maybe these scenes of Chit contrasted with Som, and that's what probably attracted Wee to Chit, because even in the worst situation, she still cares for other instead of talking trash.
