Well, little one, a war bride means a woman who married a soldier during or after a war. But in this case, it's a man who married a soldier! Isn't that interesting?
So imagine that there was a big war happening and a soldier who was fighting in the war met a man and they fell in love. When the war was over, the soldier had to leave and go back to his home country, but the man really loved him and didn't want to be separated from him.
So, the man decided to go with the soldier to his home country and live there with him. This makes the man a war bride because he married the soldier and moved to a new country because of the war!
Sometimes, when people move to a new country, it can be a big adjustment because they have to learn a new language, new customs, and make new friends. But as long as the man loves the soldier and they support each other, they can make it work and live happily ever after.
