One thing about Leia was that she wasn't afraid to pitch in and help out when needed, despite her title as a Princess. So when they had originally landed on the frozen planet, she saw no need to slough off helping out. Helping to set up various equipment in the subzero temperatures though had been hard on her skin and when she accidentally bumped into a metal poll she was left with an ice burn on her cheek.
Of course that's when HE showed up. Han took her hand and lead her to that heap of a ship. "Come on, they won't have the medical area set up until at least tonight, at the earliest."
The gentleness in his touch as he rubbed the burn cream into her cheek had her closing her eyes. She really didn't need to fall for him, but he surprised her all the time with his odd brand of heroism.
When he stilled his touch she opened her eyes and felt her cheeks heat with a blush.
"Thanks," she whispered to Han.
"Sure," he whispered back and gave her one of those charming grins.
She really didn't need to fall for him. But she had a feeling it was already too late.
