Sirius had one secret. One secret he coudn't tell anyone.

They'll probaby just laugh at him.

Or ignore for the rest of his life.

There was one person he told. One only, and that was James.

"What do you want to tell then? And don't make it too long, I have practice." He asked when they got in an empty classroom.

"I... I..."

"For Merlin's sake, Sirius, say it!"

"I think I love Moony."
