1. If he's sad, give him tea with complimentary macaroons. 2. If he wants to move on, delete his ex's phone number and pictures from his phone. 3. If he wants revenge on his ex, kick him out of your house. These were the three simple rules that Serena had to follow to keep up her reputation as a breakup expert at highschool, because her virtue at healing broken hearts had made her popular and loved. She had nothing to regret. But Serena has to break the third rule when her client is no one other than her former childhood best friend, whom she had grown apart from in middle school. Now she has to heal his heart just as he used to heal her wounds when they were younger. As well as keep herself from falling for him. Again. Not forget to mention, all the traumatic incidences from past that flood back into her mind.
