Legal Wife (1986)

Arunprapai is a perfect woman who has the looks and the quality. She married to Kongkai, the man she didn’t love, because she wanted to escape the rumor about her having an affair with one of her best friend. But her family life is not as happy and smooth as some other peoples, the same with Kongkai, because Prungchat, his former lover is still coming around. So, getting a divorce seems to be the obvious choice.
