Paano ba malalaman kung siya na ang "the one"? For Audrey, wala siya ideya talaga. Kahit may sarili siyang mundo kapag nagsusulat, pulos kamalian pa rin ang napapasukan na relasyon. At kung siya ang tatanungin, ibabase lang rin niya ang lahat sa nababasa. Simply because she settled that romance or love isn't for her. Not until her first crush reappeared! Luis Antonio Illustre is sick, and to iron things out in his life, he starts by helping Audrey to write a romance novel to be her hero. But how will he admit to the woman who piqued his interest years ago and now that he's sick? By engaging in a 100-day agreement to help one another, re-discover love and friendship under one roof! And another question is, who's most likely to fall in love first?
