While 30sai focuses more on the BL romance in an office setting, Shujin-ko has multiple mains with one storyline being a BL also. I recommend both because they both have a refreshing take on BL that I can't really elaborate well without spoiling haha (especially Shujin-ko)

Both dramas are heavy and emotional which focuses on family relationships. Go Ahead has more comedic and romantic sides while Beautiful World has mystery and school stuff.

Both are coming-of-age stories with a touch of bromance and slight romance. While Kids on the Slope mostly has jazz songs, Little Love Songs focuses on stories behind real songs by a real band. Both are emotional and heartwarming,

Both have amazing OSTs and cinematography. Both stories surround the mysterious circumstances of a student's fall from the rooftop. Both have really good lines and chemistry between all the characters.

Both are thrilling and emotional. Two Weeks is a chase of a father desperately trying to live in order to save his daughter while Tunnel is about time travel of a detective sent to the future.

Both are heartfelt dramas about life in different workplaces. Incomplete Life is in an office setting while Hot Stove League focuses on off season of baseball. Both have great acting from the ensemble and also gives variety of feels and emotions.

Both are about baseball. While Our Baseball is a mini-series focusing on the struggle in everyday life and baseball, Hot Stove League is a drama focusing on the preparation season for a baseball season. Both have excellent OSTs and the stories/acting tug the heartstrings.

Choo Ja Yun's character is an elder sister in Unfamiliar Family while she is a mother in Beautiful World. Both series shows family values and love.

Both are set upon cold cases. Both are very emotional and great OSTs especially in Cold Case: Shinjitsu no Tobira.

Both highlights friendship between a young man and a grandmother who are not blood-related. Both are comedic and very emotional.

Both are about brothers (My Annoying Brother is a Korean brother-brother film while Go Brother! is a Chinese brother-sister film) and they show realistic depiction of relationships of annoying siblings. Both are comedic yet at the same time both these movies wrecked me emotionally by the end.

Both are about friendships and last wishes of a very sick person. While "My Friend Is Still Alive" is a korean drama special, "The Last Wish" is a chinese movie. Both are emotional and comedic at the same time.
