The Fierce Wife 2018 (2018)

Aruna and Thada are happily married and completely devoted to each other. Suddenly one night, Aruna's cousin Kunya shows up at their door.

Kunya causes issues around the house. At work, Thada's rival Munin demands results.

Kunya asks Aruna if she can move in with them for a while. While visiting Tharee at work, Aruna meets a handsome young man.

Aruna feels a little uneasy when Thada tells her he'll be taking a business trip out of town for a few days — with Munin.

Kunya wears Aruna's beautiful new red shoes to her job interview with Munin. While cleaning the house, Aruna makes a discovery.

Thada is evasive when Aruna asks him what he was doing all day. Mr. Suchart summons Kunya to his office for a meeting.

After leaving Kunya at the office, Thada takes his jealous passions out on his wife. The next morning, Aruna tells him she wants to go back to work.

After talking to her daughter, Aruna tells Tharee that she wants to get a job with her. The rivalry between Munin and Kunya heats up.

Thada and Kunya are almost caught red-handed when Aruna returns home with her mother. Later, Aruna talks to Mr. Wasin about her job.

Aruna starts her new job. While Thada and Kunya are out shopping for groceries together, they bump into an inconvenient witness.

Finally, Aruna confronts Kunya and tells her to pack up and leave. Thada gets pulled into an emergency meeting with Mr. Suchart and Munin.

Thada has a business trip with Munin tomorrow, but nobody in the office knows where he — or Kunya — have gone. Tharee tries to track down Aruna.

On their business trip, Thada has to fight off Munin's drunken advances. While alone in the office, Kunya sets to work sabotaging Munin.

Though heartbroken, Aruna puts on a brave face for Nuda. While in the condo he shares with Kunya, Thada thinks of his daughter.

Thada starts to realize that life with Kunya might not be ideal. Aruna gets her hair cut short and completely changes her look.

Jealous and enraged at the sight of Aruna and Thada together at the office party, Kunya gets drunk and causes a scene.

Aruna's online videos become popular. She asks Thada to come home to see Nuda, but before he can go, Kunya makes her move.

Seeing her dear friend stuck in limbo, Tharee encourages Aruna to make a decision about her marriage to Thada. Kunya shares some shocking news.

Nothing ever seems to be enough for Kunya. After arguing with her in the hospital, Thada shows up at the house to talk to Aruna.

Believing in her potential, Munin asks Aruna to make some videos for her online magazine. Mr. Suchart asks Thada to train the new hire.

Tharee notices an undeniable sparkle in Aruna's eyes when she talks about Mr. Wasin. But she wants Aruna to get back together with her brother.

Thada is out of a job and needs to watch his money, but he gets no sympathy from Kunya. Aruna films her first video for Munin's online magazine.

Aruna and Thada seem to have worked out a nice, amicable balance. But then, Kunya shows up at Aruna's house and declares she's moving in.

The fallout from Kunya's livestream causes a scandal affecting the whole family, and Thada can't forgive her. Kunya takes Nuda from her school.

Thada stops by the house to pack up his things. Before he leaves, Aruna makes him a bowl of wontons. Sparks fly between Wasin and Aruna.

To get closer to Thada, Kunya gets a job at his company, and Thada has to train her. Wasin helps Nuda out at a school event.

To finally break free of Kunya, Thada accepts the transfer to China. At the opening of the musical, reporters ask Aruna and Wasin if they're an item.

With nowhere to go and nobody to turn to, Kunya resorts to selling her belongings on the street. Thada returns to Bangkok for a visit.
