I don't think Nao is a hypocrite because she's able to suppress her feelings and not act out of selfishness like her other two friends. It's true, she does have feelings for Thrai, but the thought of pursuing a relationship with him stopped right after he tried to rape her. I really give props to women who can control their feelings after knowing that the man is no good for them. In addition, Aom doesn't back-stab her friends by flirting with Thrai behind their backs. She tries the best she can to avoid him and warns her friends. She was even willing to let him marry Min, only if he truly loved her though. She's been doing a lot to please everyone but herself. The only thing she did wrong was choosing sides. When she was with Min, she said she's on her side and when she was with Dao, she told her that she will give her all the support she needs. If my best friend was asking me to side with them when they're wrong, I will not. Instead, I'd sit them down and explain to them why what they're doing is wrong.
