Alecsandra Rei Dela Cruz wanted to prove herself to her father that she can also be a reliable person and she's as good as her brother when it comes to providing services and securities to the rich. She wanted him to be proud of her, too. She got the opportunity to do it when she finally got her assignment, and that is to guard the President's son, Nathaniel Araneta. The job was easy, she's trained to do it. What's hard was to get along with the snobbish man she's guarding and hearing his side commentaries while she's doing her job. She thought she could endure it all and just let him be an ass like he's used to, but after he got drunk and something happened to them, and he began taking care of her, it felt like she's up for a more challenging assignment-the one that is the ultimate rule of their organization. That is not to fall in love with the client. Will she be able to stop herself from falling and uphold their organization's principles or fall in love with the one who made her feel most alive?
