Lock Me Up, Tie Him Down (2014)

Same quirky vibe w/ crazy supporting characters. A cheating spouse(s), rich people, and materialistic individuals from all walks of life. But the romance trumps all. Cute and sweet. Seriously.

Both stories involve an unwanted guest wanting to occupy one's house for their own purpose, no matter how ridiculous and contrived.

A woman who loves her husband dearly but due to unforeseen circumstances forms an odd relationship with a stranger (another man).

The song "Yumeji's Theme" by Shigeru Umebayashi that's featured predominantly in "In the Mood for Love" plays at one point in "Lock Me Up, Tie Him Down". Main leads find solace in each despite one of them being married.

The main leads come together due to fate and unlikely circumstances. But their past prevented them from seeing each other sooner.

Main leads encounter fate when they meet under unfavorable circumstances. Unexpectedly, the leads have a deeper connection than anyone would have guessed.
