Answer:
The term John Gottman would use to describe Quang and Nguyen is: volatile couple.
Explanation:
According to John Gottman, there are five types of couple: conflict-avoiding, validating, volatile, hostile, and hostile-detached. The first three types are "happy" couples, even if the partners fight and argue. That is the case with Quang and Nguyen, who would be classified as a volatile couple.
Volatile couples often have conflicts. They can be very emotional and intense in their discussions. However, the same discussions are usually permeated with humor and laughter. Even if they choose to express their anger, the partners are not disrespectful toward each other. Also, the boundaries between their individual lives are mostly undefined.
