Donnie couldn’t help but to let out a giggle and a blush form on his face as he looked at you entering the lab, and felt his heart pounding.

"I've missed you so much, dear." He began to smooch your cheeks and hug you, which was surprising to you! He wasn't into PDA, but you didn't budge.

Shelldon watched from across the room, Donnie forgot for a second he was there. He beeps loudly: his heart rate was raising.

"Woah! Too much PDA, I see." Donnie was bashful, blushing heavily.
