I think the authors often choose high schoolers because they are in the right age to develop love. Middle schoolers for platonic love, high schoolers for love at first sight, or without knowing the other one too much. College is for love in every way. Distance, poly and so on could be here.
Just a thing I see connected here, this isn't set in stone.
The fact they are in college in not in high school is another reason why this is top tier. Artist can draw and make a story with free will and more often than not, authors abuse it and use it to sexualize highschool students.
I like how the author made the characters more human. Humans are selfish creatures and won't stop until they get what they want and to top it all with an obsession bloomed from love was entertaining to read. If you analyze the characters they each possess the all traits mentioned. The art also complimented the great story. This story didn't have that cliche shit i often read in mangas so it was worth the time.
