I Will Not Be The Supporting Character Forever

She opened her eyes to find herself reincarnated as a minor character who had fallen from grace due to a brief, careless mistake. “So, I’m neither the lead nor a wealthy heiress—just an extra character who’s destined to cause trouble!” To escape a life of forced servitude, ‘Elena,’ a humble servant of the divine, decides to conceal her commoner origins and becomes a theology instructor for the emperor’s younger brother. With this plan in mind, she thinks she’ll be able to quietly observe the budding romance between the main characters, the teacher ‘Rosaline’ and the story’s male lead, eventually securing her own peaceful future. However, things take an unexpected turn when her identity is exposed, and Rosaline confronts her. Soon after, she finds herself caught up with the male protagonists, unintentionally stepping into Rosaline’s role. But wait, wasn’t that supposed to be the protagonist’s part? Yet, despite the fierce attention of these men, Elena’s heart is drawn only to the unassuming apprentice knight she happened upon by chance.
