So monogamous romance, ordinary people and slow burn...
Cunning Single Lady Funny show, people are in love with the leads though. The ML is a CEO but totally breaks the mold.
Descendants of the Sun Ordinary people, monogamous, natural progression of a romance.
It's Okay, That's Love Natural progression, ordinary but successful people, the ML is a successful jerk but they both met their match.
Go Back Couple Very much like familiar wife.
Lucky Romance monogamous, ordinary (yes he's a ceo, but not insufferable at all), slow burn and very quirky tone.
The Happy Loner 2h drama, extremely ordinary yet quirky characters.
Weightlifting Fairy Kim Bok Joo They both are high ranked athletes but with ordinary lives (blue collar but not miserable, and upper middle class backgrounds), monogamous with a 2nd FL.
Heart to Heart Not yet done watching but the leads seem very human to me and quite quirky in a very 'normal' way. Not really a slow burn, but very natural progression
The Queen of Office There's a ceo but he's pretty bad at playing games, both leads are quirky and the show is super funny. Ordinary office setting.
