I think it’s similar because it also has school setting and continue on to adulthood. It’s also realistic and deep. I recommend you to watch it. Enjoy ^^

Both male leads are good at fighting and are undercover (although one is a cop and the other is not). Female leads are both fierce and are strong-willed as well.

If you were a fan of A Journey to Meet Love, the City Hunter has romance, comedy and great action scenes!

Both are crime/investigation/Detective dramas, and both are so very complex and twisted that they leave one hanging at the edge of the seat. Absolute amazement.
There are a few more similarities however due to potential spoiler reveal I cannot name them. There is however a high chance that if one liked the one drama, the other one will appeal as well.

male lead gets into relationship with female lead for revenge but ends up falling in love with her.
male lead is abusive
male lead and female lead's fathers were in business together, one betrays the other.

The last part of this The Lost Tomb 2's story is taken from another story Eagles And Youngster. The whole drama is like a sequel between Eagles And Youngster and Sea If Tombs to add in to this The Lost Tomb 2.

They are under the same genres: romance, school, youth, friendship, slice of life.
I feel like My youth has a similar setting to River flows to you. This focuses on friendship. The boy is always there for the girl no matter what. There are rivals too ;)
RFTY shows a boy and a girl who grew up together and one eventually falls in love with the other, which is quite similar to my youth .

Differences

River flows to you has more family involvement

The girl is very poor in RFTY

Few friends

both psychological dramas and tells the story of people going through trials
both are very dark, good stories
