They both have very similar vibes and Park Min Young plays nearly identical characters in both. If you're looking for cliche rom-coms to make your heart flutter, you're gonna dig them.
Both showcase healthy relationships between the leads and deal with their emotions in a very subtle and sensitive manner. They are both rooted in reality and deal with prevalent issues without being preachy or boring. It's definitely refreshing to see male leads respecting their partners and giving them their space. They are both slow romances, Radiant office more so but that's part of what makes it so gratifying at the end. They are not your typical K dramas and are hence grossly underrated. They are not for everyone but they're definitely worth your time.
