For as long as he can remember, he has loved the girl next door. She was his childhood friend, his first crush, and the only person who ever made him feel noticed in a home where he was constantly overshadowed by his sister. While his parents praised her every achievement and dismissed his own, He learned to accept being second best—at home, at school, and in life. But the girl wasn't the only one watching him. Her older brother, once his relentless bully, spent years making his life miserable. Teasing him, provoking him, and always finding a reason to get under his skin. What he never knew was that behind the cruelty hid feelings the boy didn't understand—feelings that slowly twisted into an obsession he could never shake. After a falling out between their families, he loses contact with them for years. Now, as a high school senior, he's back. Returning to his old town means reuniting with the girl he's loved since childhood. Older, prettier, and just as charming as he remembers, she welcomes him back into her life with open arms. He quickly finds himself falling for her all over again. But her brother is there too. Older. Quieter. Watching. And despite the years apart, he hasn't forgotten him for a single day. As He settles back into his old life, the brother begins noticing things nobody else seems to see: the exhausted smiles, the constant apologies, the way he flinches when his phone rings, and how quickly he dismisses his own accomplishments. The more he learns about his home life, the more horrified he becomes. Because he isn't just overlooked by his family. He's being emotionally neglected by the people who should love him most. Determined to make up for the hurt he caused years ago, the brother secretly starts protecting him—offering support when nobody else does, standing up for him when no one notices, and becoming the one person he can rely on without realizing it. Meanwhile, he begins to uncover uncomfortable truths about the girl he's loved for so long
