"No commitments. No expectations. And absolutely no falling in love." To the world, Pik and Jai are the golden boys of the popular T-Pop group APEX. They share everything: a stage, a past as university students, and a strong chemistry that neither of them talks about. Pik has secretly been in love with his best friend for years, hiding his feelings every time Jai-the industry's well-known flirt-openly dates other people. But under the huge pressure of fame, the lines between them slowly disappear. They end up in a toxic friends with benefits relationship, where Jai acts like a caring boyfriend when they're alone, but quickly hides behind the words "we're just friends" whenever things start becoming too serious. As jealousy grows stronger and their friendship turns into an emotional roller coaster, they have to make a choice: stay safely apart, or risk everything for real love?

"If we're just friends... what kind of friend sleeps on your lap, demands you to pat his head, and posts pictures of you online just to call you cute?" To the public, Pik and Jai are the entertainment industry's favorite duo. But behind the scenes, Jai is a walking red flag. He draws strict lines under the studio lights, telling the world they are "just family," while privately blurring every boundary until Pik is losing his mind. Pik is tired of smiling through the heartbreak. How long can you stay in the friend zone when your "best friend" refuses to let you go, but refuses to love you back?
