There's the law stuff that isn't the main focus
Mystery
Sfl is same
Haven't finished you honor yet but so far seems similar

If you decide to watch either one you will realize they are very similar both girls know ml before sister gets married

This will give the same feelings
Both have a good story
Amazing visuals drawing closer is newer so it does have more modern effects.

Both are worth watching

Both have an older style and the male leads intentionally approach the fml for a purpose sorta have the same feeling

Idk if this was mentioned on not but I've been looking for things like this and finally found something close enough both have revenge which also involves getting closer to the girl to get their revenge

These are pretty similar because of the second female lead tieing down the male and the ml kinda give the same gloomy vibe

While I was watching these is felt that it was pretty similar both ml and leads love each other but life plus the second leads push them further apart

I guess it's sorta similar both have queen in the title . Both have to do with rekindling guess if ur having withdrawals u can try this

Has the gf meets the ex girlfriends and theres 4 instead of 2 it's pretty funny and light hearted it reminded me of it
Has the sismance if u want a longer series I guess this is it.
