It's my second recommendation for Age of Youth as I was literally amazed, felt so good watching it.
Both have super awesome Soundtracks ( with foriegn songs).
Both have amazing performances from the actors and actress.
The storyline from both drama evolve friendship, romance mixed with some good comedy. Aside from that they are unique and different from each other in term of overall plot.
Both of these Masterpieces gets 10/10 from me. (Gladly)
Enjoy your watch :)
