Master of the House ending explained: Who Killed Roongroj?

The ending of Netflix's Thai murder mystery show Master of the House is quite predictable and dark. It deals with a murdered wealthy diamond tycoon; however, it explores no new themes other than what people are used to: power, treachery, and vengeance.

In the final episode of Master of the House, they try to close all loopholes and end it satisfyingly, but after everything, you can't help but wonder if the story is that deep or unique. It's about Kaimook, a servant who becomes the bride to Roongroj right before he dies, and her quest to find out about his murder.

As it unfolds, it will undoubtedly be clear that Kaimook premeditated the murder with some other mistreated servants and made it look like Roongroj's sons, Phupat and Mavin, did it. Although Master of the House sticks very closely to a cliche, it tries to tell a story about revenge and justice from Kaimook's viewpoint through the use of butterflies, which mean freedom and captivity.

Who killed Roongroj on Master of the House?

Master of the House is a murder case involving Roongroj, an ultra-rich diamond magnate, and two main suspects: his two sons, Phobat and Maven. Both brothers gain enormous riches, and sibling rivalry makes them prime culprits. However, this storyline is interesting because it is framed from the perspective of Kaimook, a maid who becomes one of Roongroj's wives.

Kaimook has an idea to kill Roongroj with the help of other mistreated servants. They arrange everything so that, after they are done killing both Roongroj and Mavin, Phuphat will be the one who they blame for the committed deeds. The main idea is to provide a video indicating that Roongroj gave his assets to Kaimook and footage that makes it look like Phuphat was guilty.

The reason is simple: Kaimook will get payback for all the bad treatment they endured from Roongroj and his family on Master of the House. Kaimook had to face abuse since the day she was recruited for employment, and her situation kept getting worse with time.

Roongroj, who falsely believed that with his money and influence, he could treat people, especially women, like trash, drove Kaimook to a point where she decided that she would never be broken like Dao, a maid who committed suicide because of the tragic treatment at the hands of the same person. She manipulated Roongroj into marrying her by telling him she could provide him with a good, loyal heir in contrast to his treacherous sons.

Kaimook wants revenge because Roongroj has treated her and the other servants badly. It started when she went for a job interview, and things got worse from there. Roongroj was so mean that one of the other maids, Dao, killed herself. Kaimook was also struggling because Roongroj wouldn't leave her alone.

Roongroj also falls crazily in love with Butterflies because he wants to own and dominate them. He keeps them in cages, just like his servants. This theme runs through the series, relating the butterflies and the human characters together.

One day, Kaimook devised a revenge plan: to marry Roongroj and become an influential force in the household. She convinced him she could bear an heir who would never betray him as his sons did. The manipulation worked on his fears and desires, and so he married her and gave her control over his assets.

Kaimook contrived a fine idea by which she would incriminate Phupat for Roongroj and Mavin's death, saying that she spiked their liquor with his fun drugs. Now that Roongroj and his sons are out of the picture, Kaimook and the rest of the servants can finally attain freedom. They throw the family out of the mansion, hang up pictures of themselves, and throw a big party.

Still, it is hard to shake off the feeling that old power dynamics and humanness can bring back all those problems they are trying to leave behind.
