The gang always just thought Harley was shy. They really tried to do lots to break Harley out of his shell. Always involving him in plans, taking group photos with him, eating lunch with him, playing video games with him, etc. Harley always just snuck glances a lot, but over time he learned to be a lot more discreet. They became his friend group and he didn't wanna lose them after all.

But when they found out though? THAT is a different story. :D
