The story is divided into 3 parts: Bakit (Why), Sino (Who), and Paano (How)

Bakit (Why) Jian and her previous boyfriend Requim saw each other in a mall. In a flashback, Jian was reminded of how happy their relationship went and how he told her he did not have a reason why he loved her because he believed that once the reason fades, the love follows. Back to the present, Requim's now girlfriend, Erin, was also there at the mall. She hugged Requim from the back and the two left, leaving Jian behind.

Sino (Who) Erin and Requim were sitting in a cafe, discussing their eventual breakup that Requim initiated. In a flashback, Erin was reminded of how she saw Jian and Requim looking at each other at the mall. Noticing the tension, she ran to Requim, hugging him from the back. While they were leaving, Erin asked Requim if that girl was his ex-girlfriend. Requim agrees. Walking home, Erin told Requim that whatever happens, he should be honest with her, even if she is going to be hurt by the truth. Back to the present, Erin asked Requim if she was just a rebound girl. Requim answered, "I loved you."

Paano (How) Continuing from the breakup at the cafe, Requim was reminded of how Jian told him how she wished that her love for him would immediately disappear once they broke up. He also thought of the time when he and Jian broke up because he needed space, which is parallel to the reason why he broke up with Erin. At his house, he tried to take the breakup with Erin as calmly as possible while being reminded of how violently he reacted when he and Jian broke up. In the end, he can be seen holding a mended broken vase, a gift Jian gave him.
