Both the shows are highschool shows but done correctly with everyone giving their maximum efforts. Both are about the Love story of student council president and head of music club. Both these shows have leads who are really great at acting with amazing, mind-blowing chemistry.
My school president is a fluffy show with lots of music which touches our soul but with minimum angst. Lovesick is very angsty with unrequited love, longing, pining, yearning etc. Infact both of these shows are breath of fresh air and could be enjoyed by any age group of people. These two portrays the innocence of youth,slice of life etc.
