In episode 43 of "My father, the one who stays", the family of Mr. Chinh ( Meritorious Artist Bui Nhu Lai) and Mr. Binh (meritorious Artist Thai Son) will have to make a difficult choice.
Because Viet (Thai Vu) discovered that Nguyen (Tran Nghia) had feelings for An (Ngoc Huyen). When Viet directly asked "Do you like An? , Nguyen was stunned and could not explain.
After that, Viet discovered An and Nguyen going out together and asked them to sit down and talk. At this time, Mr. Chinh and Mr. Binh also appeared with serious faces.
Looking at the attitude of Viet and the two fathers, Nguyen predicted what the family would bring about at the meeting.
Nguyen and An's feelings for each other were more than brothers, which was a big shock to themselves and other family members.
They will have to make a choice, or prevent An and Nguyen from maintaining a brotherhood relationship after many years of living together, or support both of them as a couple but could break up the family if they broke up.
It was a difficult decision for the whole family. Meanwhile, Nguyen understood better than anyone that he could only trust and be close to one girl, An - who grew up with him under the same roof.
Viet was angry and sad when An and Nguyen did not confide and share their feelings with him. Nguyen himself was also surprised because the relationship had not been named but had been discovered by his family.

In the original Chinese version of "In the name of a relative", the prototype of the characters An and Nguyen became a couple, then got married.
With the Vietnamese version, many viewers still have mixed opinions about the love of the two Nguyen brothers.
The fact that they lived together, grew up together, and had complicated families... made An and Nguyen have many barriers, unable to come together.
With more impact from family, they will have more difficulty choosing between family love and love. However, the audience believes that An and Nguyen can become a couple because they trust, understand and sympathize with each other.
Previously, An and Nguyen's relationship was unclear. The audience only saw Nguyen's feelings, such as being jealous when An was with another son or being angry when An was making aises to someone.
After knowing many guys, An also understood that only Nguyen was patient and ready to protect her from the storm.
