When Dane Perez—the hottest and probably the haughtiest member of the popular school band, Treble Five—gets rebuffed by the girl of his dreams, Barbs Flores, he finds himself in a slump. Dane’s Treble Five barkada comes up with an ingenious plan to not only get Dane’s groove back, but Barbs as well. Ang plano? Kailangan pumili si Dane ng isang ‘unlucky girl,’ make her fall in love with him, and then break her heart… all within 100 days. Naniniwala ang barkada niya na once makita ni Barbs si Dane with another girl, she will totally want him back. Ang napiling ‘unlucky girl’? Si Kate Borja. Simple, innocent, and romantic, Kate gets to spend time with the school’s most popular guy. What she doesn’t know is that she’s in for the biggest surprise (or heartbreak?) of her life! Things take an unexpected turn nang magsimula ng ma-develop ang feelings ni Dane para kay Kate. Coincidentally, ang best friend niyang si Luis ay in love din kay Kate. Will love destroy their very solid barkada? Or will Dane and Luis willingly put their love for the same girl on hold just to save Treble Five?
