Michael Teo

Michael Teo is Astrid Leong's ex-husband and father to her son Cassian Teo. He is a secondary character and later one of the main antagonists in the Crazy Rich Asians book series by Kevin Kwan.

Background
Michael is a former Army technology specialist turned businessman and entrepreneur. Astrid first saw him at a fashion show where he was modeling a speedo, much to his embarassment. They later meet again and are instantly attracted to one another.

After his marriage he struggles to gain acceptance due to his humble background, but after the success of his business, he becomes more respected in the family.

Personality
Michael was first introduced as a defeated, but otherwise caring husband and father who only wants the best for his wife and son.

However, after his business becomes successful (due to the secret investment of Astrid's former lover Charlie Wu), Michael's personality shifts dramatically, and he becomes a highly self-centered and controlling husband.

Novel
Michael is unhappy with his marriage to Astrid due to him constantly being looked down upon by his old-money in-laws. He fakes an affair in Hong Kong in an attempt to get Astrid to divorce him, which initially succeeds before Astrid uncovers his duplicity. They eventually reconcile by the end of the book with the intervention of Astrid's former lover Charlie Wu, who wants Astrid to be happy.

Film
Astrid leaves him after discovering him having an affair with a mistress. Unlike in the novel, Michael in the movie is actually having an affair.

China Rich Girlfriend
Michael's tech start-up booms to success, which is actually due to Charlie Wu's secret investing in the company in order to help Astrid save her marriage. However, success changes Michael's personality and makes him more tyrannical and controlling, eventually leading to Astrid leaving him with their son Cassian.

Rich People Problems
Michael conspires with Charlie's ex wife Isabel to ruin Astrid's reputation and tries to extort money from her in their divorce settlement. He finally agrees to sign the divorce papers when Charlie Wu threatens to reveal what he has done to the police.
