Lost Love Never Returns
Leona Langham and Sebastian Kane are the match made in heaven that's acknowledged by the entire school.
Sebastian is the hottest guy in school. He's tall, lean, and has an extremely handsome face. Oftentimes, he wears a black windbreaker that makes him look like a protagonist from an action comic. Many girls find themselves falling head over heels for him.
Unfortunately for them, Sebastian only has eyes for Leona. They are childhood sweethearts who have grown up together.
They celebrated their first birthdays together. When they turned seven years old, their families betrothed them to each other. When they turned 14, Sebastian gave Leona a love letter. When they turned 16, Sebastian confessed to Leona. When they turned 18, they promised to apply for the same university.
But on their senior year, a new transfer student named Maureen Shadwick joins their class. The homeroom teacher specifically assigns Maureen to Sebastian when she's organizing pairs for the tutor sessions.
She stresses to Sebastian, "If you don't accept this assignment, you can forget about maintaining your relationship with Leona at school."
