• Related好一対こういっついWrittenSays two people or things are very well matched, with a complimentary tone, as in 「好一対の夫婦」; it has a strong written flavor, while 「アベック」 only says they go together.

For a couple today, say 「カップル」; 「アベック」 sounds dated. Use 「つがい」 for mated animals, 「一対」 for a matching pair of things, 「二人組」 for any twosome, 「好一対」 in formal praise of a well-matched pair, and 「一人」 for being alone.
