What i loved:

the school part where they formed a group and stood for each other
there was no melodrama on silly things like not getting to same college , stream , class etc etc. They were mature about it. In one of the famous cdrama ML was ready to change streams just bcs FL was alone in a arts class. i couldnt continue watching after such stupidity from characters. Here even after getting together they were mature about it
FL being mature and outspoken when needed. I loved how innocent but at the same time strong the FL is.
Second pair story was great too

What i didnt like
College years and working years were cute to watch but nothing new in terms of freshness. We can see where it is going unlike school years so not that exciting but thats just a small -ve point.

Overall a great youth story after Lovely Us and Flourish in time!
