I Almost Slept With My Best Friend's Boyfriend by MistakeEpisode 5

Emma spends a night at her best friend Amber’s home, where Amber’s boyfriend James mistakes her for Amber and nearly crosses the line. Later, Emma discovers Amber betrays her twice: flirting with Emma’s suitor Joey and drugging Emma to hand her over to client Tom for a project. Saved by James, Emma learns Amber lied—she stole Emma’s identity as the girl who saved James years ago. After exposing Amber’s schemes, James proposes to Emma, his long-lost true love.
