Luna and Kalix were still students, when their budding romance was cut short. Years after, fate finds a way for them to work together on a special project.
When Luna, an architecture student, meets Kalix, a pre-law student, she knows it's love at first sight so she makes the first move. Years after, Luna, now an architect, bumps into Kalix, now a lawyer, again but all she has for him is hatred.
Luna finds herself on Kalix's bed one morning. Via, Sam, Yanna and Kierra ask her about their real status, but she's as confused as them because she doesn't know if Kalix and Amethyst, a pre-law student, are together.
Luna and Kalix spend their first romantic getaway as a couple in Boracay. Meanwhile, Kierra introduces her "boyfriend" Miguel to the girls. They start to suspect something is not right with the guy.
Blaming herself for what happened to Kierra, Luna is at her lowest point. What makes it worse is that she finds out about Kalix's cheating. It is the end of LuKal?
Many years later, Kalix asks Luna to be the lead architect of his resthouse in Tagaytay. All conditions are met by Kalix to make sure he'll get her "YES".
Kalix and Luna together again... but just for a special project. Now that Luna becomes more open to work with Kalix, will she start to reopen her heart for him?
All professionals now, Luna, Kierra, Yanna, Via and Sam set a vacation in Boracay. But as she tries to open her heart for him, her unresolved issues with Kalix resurface.
