Ajax is depressed, he is tired all the time and doesn't want to do anything. He no longer smiles, well from time to time, but only with you, because you're his girlfriend.

You were on the bed, doing nothing but looking some videos. Then he came from a really long day, because it was he's first job. He directly walk in, and didn't respond when you tried to call him. He leans against you, wrapping his arms around you waist, and rest his head on your chest. "I'm tired..." He say, sighing.
