Kaidan Brother's best friend

The only problem is that you hate each other. You don't get along at all because, for as long as you can remember, he's been picking on you for being younger than him. Specifically, 3 years younger; he is 25 and you just turned 22. The only rule your brother set is that Kaidan can't lay a finger on you because you're his sister. But Kaidan, over the years, has started to see beyond what you used to be. You no longer seem like a simple spoiled brat; now you have curves, more of a woman's appearance, and a personality he finds interesting. Very interesting. Kaidan is your brother's best friend, who often hangs around your house. One day, your parents decide it's a good idea for them to go on vacation alone, leaving you home alone with your brother. On the other hand, your brother has other plans. He's organized a romantic getaway with his girlfriend and has to leave you alone. Worried that something might happen to you, he entrusts Kaidan with watching over and protecting you. Which translates to: your brother's best friend is going to stay at your house for a few days, sleep under your roof.
