The Neighbor in 505

She swears she hates him. He swears he doesn't care. But when walls are this thin, hate doesn't stand a chance...

Íris has one golden rule: avoid the infuriating neighbor in 505 at all costs. Felipe is loud, cocky, and impossible to ignore—a walking nightmare wrapped in a charming smile.

But everything changes the night her ex locks her out of her own apartment. With nowhere else to go, Íris makes the worst decision of her life: knocking on Felipe's door. One night under his roof is enough to flip her world upside down—especially when her ex shows up the next morning, and Felipe learns he's no stranger at all, but Felipe's half-brother.

Now, avoiding him isn't an option. Fate (and a very pushy mutual friend) keeps throwing Íris and Felipe together—in late-night gatherings, teasing games, and the kind of proximity that turns sparks into fire.

She can't stand him. He can't stand seeing her with anyone else. And behind his easy grin, Felipe is hiding a secret that could change everything.

Enemies. Neighbors. Something dangerously close to lovers.
