Crossed Wires - Neighbor!Frank Castle
You were meant to send a teasing photo to the guy you’re seeing. Instead, it lands in the hands of your dangerously attractive neighbor, Frank Castle. One wrong text turns into undeniable chemistry, late-night encounters, and a supposedly “casual” arrangement neither of them is emotionally prepared for. With secrets, an almost-boyfriend, and two friends who see straight through their bullshit, keeping things uncomplicated might be impossible.
