I'm looking for a trilogy that I read about three years ago. It's a bit of a cliché, it starts with the teenage protagonists where he's rich and she's poor. It seems that her mother or father worked at his parents' house, and they study at the same school, they are in love with each other but they never really spoke, after a party they sleep together and admit their senses but some things happen I don't remember and they split up. Years later he becomes a CEO it seems she starts working at his company. If memory serves me in a high school flashback, they weren't together, she catches him delaying with a girl in the room and they stare at each other.I read it in 2019 but I think it was written around 2016. If anyone can help me I would be very grateful ❤️ sorry for my bad english
