Oshi no Shuuchakushin wo Nameteita

Estefania worked herself to the bone for her family's sake, while they took her for granted. One day, Estefania realized that, reincarnated in the world of her favorite novel, she was a supporting character who didn't have much time left to live. She closed the book on her days of living in her family's shadow, and set out to meet her favorite character, the Grand Mage Synil Crown. However, as Synil is cold-hearted and ruthless, she thought she would be satisfied with just seeing him once, but before she knew it, she became the target of his attachment―!?

"S-Synil-sama, isn't this a bit too close...?"

"In what way?"
