Trapped finger

He was the boy next door. My brother's best friend. The one who promised to marry me when we were eight just to hide my shoes . But at thirteen, the world went cold. Yuta became a stranger, a "Gatekeeper" who watched me from the shadows but never let me in.

Now, Yuta is a genius medical student with a protective streak that borders on terrifying. I'm an AI programmer trying to find my own way. We share an apartment, a history, and a million unspoken words. He scares off every guy who looks at me with a single "brotherly" glare, claiming he's just protecting Haru's little sister.
But between the heated arguments in our kitchen and a snowy Christmas Eve at a lonely mountain cabin, the logic is changing. The "Gatekeeper" is tired of guarding the door-he wants to own the heart inside.
When the power goes out and the silence finally breaks, will we find our way back to the promise we made fourteen years ago? Or is some code too broken to fix?

What to expect:

• ✨ Protective/Possessive Male Lead
• ✨ Brother's Best Friend
