Nur Zya Syirah Zofia, better known as Yira, works as a customer service staff member at a famous gym in Petaling Jaya called Titan Core Fitness. Even though her resting face constantly looks like she's mad at the entire world, customers adore her soft and thoughtful service.But Yira's life starts turning chaotic when a new gym member named Tengku Syazir Muzhir appears.Tall. Muscular. Annoyingly handsome and worst of all.. he loves getting on her nerves. Their first meeting begins with an embarrassing misunderstanding at the gym counter, causing Yira to label Syazir as another cocky gym guy, who thinks every woman melts over abs. Meanwhile, Syazir finds it fascinating that a customer service employee can look like she's seconds away from suing customers. From petty arguments, sarcastic exchanges fighting over vending machine drinks, to verbal battles in front of gym members.. Their relationship slowly changes. Without Yira realizing it, the man who annoys her the most also becomes the first man who waits for her after work every night and without Syazir realizing it.. the woman who can never express her feelings properly is actually carrying far too many silent wounds alone.
