Both are sports dramas with good, but different types of humor, good romance (and for 'real' romance you have to wait quite long in both dramas).
'Whirlwind...' is more action than 'Weightlifting...' , but the second one has really great friendship and 'normal life' plot.

Both are about 'normal life', but you still enjoy it even if 'nothing happens' :) And it has great humor.

Both are actually showing something that I would call female version of bromance and just a normal life.

Crimes, mysteries, with leading couple getting close from 'we know each other' to 'we're couple'. Both dramas are quite funny and entertaining.

Both are 'YG-dramas', with Winner (NTH was a member of Winner) members as male leads. Both are short, so it's easy to watch it 'at once'.
Both have a mystery which is hidden by female lead.

Both 'YG dramas' so we I had similar 'feelings' watching them.
Both of them have the same lead male.

Romance is important part of plot, but doesn't cover the rest, which is dark, mysterious, more 'for adults' I would say.

Dark dramas for adults.
Crimes.
Mysteries.
'Love me...' focuse on romance also.

Great humor and 'friends-turned-couple' type of dramas :D

The main couple from 'Weightlifting...' play supporting characters in 'Cheese...' and the plots have more differences than similarities, but if you look for college drama, those two are one of the best I've ever seen.

both are stories 'down to earth' - I mean, they're showing the reality, the real world and real life, and you still enjoy them!

Both of them are really exciting, every episode is different, but there is main plot somewhere hidden. And even main characters have quite good stories to share :D
