I am trying to use a noun to refer to youths in a relationship (boyfriend girlfriend), but even though technically it is correct, "couple" to me just sounds a bit too serious and old fashioned. It's more common for this age group to refer to themselves as "going out" or just "together". It's similar to the difference between "partner/significant other" and "boyfriend/girlfriend" where one is used more often depending on the age of the two.
What should I use? Below is an example sentence:
Example
They walked into the restaurant and saw a few other couples around their age.
