Sounds similar due to the gaming aspect.
The leads also had the same major in school, and similar aspirations to each other in both shows.
ML is seen as cold to others

Has a plot where the ML &FL know each other from childhood and are always bickering with each other.
ML is FL's boss in the work place.
ML helps FL to grown in the work place behind the scenes.

Modern Cdrama focusing on young working ladies' relationships, family, career in a big city. Each female lead has more than 2 men appearing in their love lives with interesting encounters.

- Same ML and FL
- Similar plot. ML got "Friend zone" in both lol
- Baifern said it's historical version of Friend zone.

It probably because I watch them around the same time but I felt they had a very similar vibe. They were family friendly series to watch. Both are about problems the female leads goes through before falling in love with ML

both younger male lead, older female lead, both student/teacher relationship, both male lead fall in love first.

Whilst "Oxygen" may deal with some heavier themes in comparison to "Kieta Hatsukoi", the couples in both series have very cute and fluffy relationships. These are both series that had me smiling nonstop and that I was sad to see come to an end.

They both have best friend still identity after female lead loses her memory in a car accident but pan Ruk pan rai is like the darker version in memory love I didn’t like how they easily forgave her and moved on like nothing happened

Both school dramas
Both double characters
School bullying
Love triangle!?
School changes
Friendships
Idol actors

Both dramas have people with unusual powers and mysteries on them. The themes are similiar and include both romance and action. Perfect choice if you're into this kind of dramas!

Nirvana in Fire also incorporates elements of espionage, martial arts and Intel profiteering. Both MCs bear similar characteristics of defining tragedies in their past and play crucial roles as strategists to reform the government, but SFD's Sam Bong is more 3D and realistic.
In terms of acting, suspense, political intrigue, character development, plot twists and character range, Nirvana in Fire falls short in my opinion. SFD is more willing to embrace and ride unpredictability in plot execution which is something that's very rare, SFD is also more lively in terms camaderie and comic relief.
Final verdict from a personal POV, Nirvana in Fire is a snorefest with bland characters and a rating of 9.1, six flying dragons is an all round masterpiece with a rating of 8.8, the contrary opinions are overwhelming so give it a shot.

Both dramas talk about revenge and justice.
It has a hint of black humor and a crazy protagonist.
Both dramas have strong women who go to great lengths to say what they want to do what they want.

Both dramas deal with illnesses and how to cope with the repercutions thereof in the ideal bl world. The directors also manage to avoid usual irritating sound effects, comic relief effeminate characters, evil females. They are definitely what bls should be like nowdays: quality production with a thought out story!

Cornered mouse is more mature, but it is also struggling with feelings and it also comes from a manga. If y like kieta, y have to see the cornered mouse also.

Both are about the professional life and struggles of modern script-writters.

Both have a girl, which talks to a ghost, who was once in love with her and revolve around making peace with him.
