Before Jayjay Mariano ever arrived at HVIS, Section E had already endured years of friendship, betrayal, heartbreak, trauma, and loss. Percy, Aries, Keifer, and Yuri were once in a car together when heavy rain triggered Aries’s trauma episode, causing him to lose control and crash. Percy was believed to have died, leaving the others devastated. Unknown to them, Percy survived. He is also Jayjay’s stepbrother because Jayjay’s father married Percy’s mother, a connection Jayjay doesn’t realize is important at first. Before Jayjay’s arrival, Ella was in Section E and became caught between Yuri and Keifer. Ella loved Yuri, but Yuri’s mother forced her to stay away from him and told Keifer to get Ella away from Yuri. Ella eventually chose Keifer, then transferred to Section A and got together with Aries. The entire situation severely damaged Keifer and Yuri’s friendship, leaving Section E terrified of another “Ella situation.” Years earlier, Jayjay and Aries had also been kidnapped together as children. Jayjay believed Aries was her cousin and had no idea he was actually her half-brother. During the kidnapping, Jayjay became overwhelmed and, in the chaos, stabbed Aries twice in the chest with a piece of broken glass. Aries survived, but Jayjay continued growing up believing he was only her cousin. Years later, Jayjay transfers to HVIS and enters Section E. The boys know she is connected to Aries and immediately fear she could cause another Ella situation. They create a plan: Keifer will make Jayjay fall for him and then break her heart, hurting Aries in the process and keeping Jayjay from becoming too important to Section E. Jayjay knows nothing about the plan. Instead of leaving, Jayjay becomes close to the boys. She becomes their Mutya—the person who brings them together and eventually becomes like family. Keifer’s plan fails because he genuinely falls in love with her. His feelings become intense, jealous, and extremely possessive. He hates other boys getting close to Jayjay and cannot stand the thought of anyone else having her. Yuri also falls for Jayjay. Then he discovers Fernandez Corp is losing money and is close to collapsing. He offers to save the company in exchange for marrying Jayjay. The engagement is arranged before Keifer and Jayjay begin growing distant. Yuri genuinely loves Jayjay and wants to protect her, but Keifer refuses to accept the engagement. He makes it clear that he will never allow Jayjay and Yuri to get married, regardless of the deal. Yuri refuses to give her up either. Keifer and Yuri begin fighting over Jayjay, and their friendship deteriorates even further. What happened with Ella is repeating itself, except this time both boys are actively competing for the same girl. Keifer becomes increasingly possessive whenever Yuri is near Jayjay, while Yuri refuses to let Keifer control her choices. Keifer’s own trauma eventually causes him to push Jayjay away. His father abused his mother before killing her, leaving Keifer terrified that the same violence will reach Jayjay. He becomes cold and deliberately hurts her, believing distance will protect her, but he still cannot stand seeing Yuri take his place. Meanwhile, Jayjay slowly uncovers the truth about her family. She discovers that Aries was never her cousin—he is her half-brother. She is forced to confront the childhood kidnapping and the memory of stabbing him twice. She also discovers that Percy, the boy everyone believed died in the car crash, is actually alive—and is her stepbrother. Eventually, Jayjay discovers Keifer’s original plan. She learns that he was supposed to make her fall in love with him and then break her heart, and that Section E knew about it. She is devastated because the people she trusted once planned to use her. But by then, the plan has completely changed: Keifer genuinely loves her, Yuri genuinely loves her, Section E genuinely cares about her, Aries is her brother, and Percy is alive. Jayjay entered Section E as the girl they wanted gone. Instead, she became the center of their lives, their secrets, their family, and a rivalry that threatens to destroy Keifer and Yuri’s friendship all over again.
