My Best Friend's Brother

Description：
Nora Wen has exactly two rules about Derek Han: he's three years younger, and he's her best friend's brother. Both are excellent reasons to keep her distance.
Derek has exactly zero interest in her rules.
When he shows up at her door one rainy night — warm-eyed, slightly drunk, and entirely too comfortable leaning against her doorframe — Nora's very sensible boundaries start showing cracks. He cooks for her, drives her places, memorizes her quirks, and looks at her like she's the only thing in any room worth looking at.
He's been patient. He's been strategic. And he's been completely, catastrophically winning.
My Best Friend's Brother is a swoony, laugh-out-loud romance about a novelist who writes love stories for a living — and somehow never saw her own coming.
Warning: contains one dangerously soft younger man and zero plot armor for the heroine's heart.
