Both are korean bl dramas that deal with both relationship and mental health issues from one of the leads.

Both are thai bl series with boss x employee leads and take place in an office setting! The bosses in both series are also painted out to be "scary" and feared by employees at first but show their sweeter side with the other male lead :)

Prapai and Sky's characters from Love in the Air are *INCREDIBLY* similar to King and Uea's characters in Bed Friend. Both relationship start off as a one night stand and it turns into them catching feelings. Prapai and King are both characters who start off as "players" who don't settle down and Sky and Uea's characters are both also similar personality wise and both have a backstory involving trauma and a shitty ex boyfriend, it's basically the same plot so if you like one of these series you'll most likely like the other!

Lonely and troubled people in lonely cities. No plot, just vibes. The cinematography/editing is also similar.
