Same high school through college time frame although ALTCFL has fl holding a one-sided crush for awhile longer and she undergoes a great deal of personal growth while ml is awesome from the start.
The male leads are initially fooled by the female leads dressing/acting as males but learn relatively early on in the drama that they are actually women. Cute chemistry all around and a quality escapism romance drama in both.
Similar girl disguised as boy plot device; similar level (high!) of chemistry between leads and both a quality watch.
