A creepy, stalker-ish guy from school has his eye on Nessa, so when her father, Aaron, is deployed overseas, he asks his best bud and ex-Navy Seal, Shane, to watch over her while he's away. But Nessa is no longer the baby-faced, awkward girl Shane once knew. She's grown into a gorgeous woman with a sassy mouth that's driving him crazy. But Shane made a promise to Aaron to look after her—not fall in love with her, and that's a promise he's determined to keep. Easier said than done... One Valentine's Day dinner couldn't hurt...right?
