A/N: This is more of a drabble than an actual story. sorry about that. Modern AU.


Zuko walked into his flat with a sigh of relief. A groan escaped his lips as he collapsed on the couch, laid his head on the back of the couch and shut his eyes.

"What's the matter?" Toph asked, "You look beat."

"I think I might be coming down with the flu." He replied with his eyes still shut tight.

"Didn't Katara have a bout of flu just last week?" She asked.

"Yeah, she did." He lifted his head and opened one eye, "Maybe I should call her to ask what meds the doctor told her to take for it."

"That's not going to help you buddy." Sokka chimed in.

"Huh?" Zuko had shut his eyes again and missed the wink Sokka sent Toph.

"This is not something that can be cured so easily." He said sagely. "You made a good decision in seeking my sister's help."

"What the hell are you on about?" Zuko asked, irritated and glaring at Sokka.

"I'm telling you that the doctors and nurses cannot help you, only my sister can."

Toph's snicker should have been a clue for Zuko but his head was swimming.

"Sokka," Zuko was sitting up fully now, "Katara wants to become a doctor. She's not one yet and won't be for a few years. And even if she were, why on earth would she be only person to be able to cure a fever?"

"Because Zuko, what you have ain't the flu. It is a far more grave than that. It's the 'Fever of Love'."

Toph's palm met her forehead.

Zuko groaned and got up. "I'm too sick for this shit," He said as he walked towards his room.

The flat, however, wasn't big enough to keep Toph's laughter and Sokka's voice from reaching his ears as he sang.

"The fever of love is like a hundred above. You are the one that turns me on."*
