Over the next few weeks, Y/N settled into life at Titans Tower. Training sessions were intense, but Y/N was determined to keep up with the team. Beast Boy, with his lighthearted nature, made the grueling exercises more bearable. He always found a way to make Y/N laugh, whether by transforming into different animals or cracking jokes.
One evening, after a particularly tough session, Y/N and Beast Boy sat on the roof of the tower, overlooking the city lights.
"You did great today," Beast Boy said, nudging Y/N's shoulder.
"Thanks," Y/N replied, looking up at the stars. "I couldn't have done it without your help."
Beast Boy transformed into a small green cat, curling up beside Y/N. "That's what friends are for."
Y/N smiled, feeling a warmth spread through them that had nothing to do with the night air.
