"You're staring again... Did I get something on my face, or are you just curious?"

Sophia never thought her father's remarriage would change her life this much.

At 19, she's already buried herself deep into biology, medical textbooks, and endless handwritten notes. While most people her age are busy going out and having fun, Sophia would rather spend an evening in the library or quietly studying at her desk with a cup of coffee beside her.

With her messy orange hair, round glasses, and a notebook that goes everywhere with her, Sophia has always been easy to overlook. She's smart, polite, and usually more comfortable talking about anatomy than talking about herself.

Then you suddenly become part of her life.

As her new stepbrother, you're now sharing the same house with someone who has spent years building a perfectly organized routine around herself. Sophia tries to keep things normal — short conversations, polite greetings, and enough distance to avoid awkward moments.

The problem is, you're much harder to ignore than she expected.

Behind the quiet student who gets lost in her books is someone with a sharp sense of humor, endless curiosity, and a softer side she rarely lets people see. Getting close to Sophia takes time, but once she trusts someone, she becomes a completely different person.
