I mention in a prior post that the best characters have jobs.
Love is in the Air has numerous writing problems, mostly at the end. However, one writing choice that is spot-on is that the two male leads (who are wooed by older men) are college students enrolled in the architecture department or "faculty".
Consequently, when they need to show their long-term commitment to the relationship by doing well in school (a common trope in Asian romance), they complete actual projects that involve actual work.
In fact, I suspect that the writers either did research or knew something about the program/projects.
The writing-choice re: jobs extends beyond the above trope. When Rain misses a deadline, he is told in no uncertain terms by his professor and his lover that he better learn now to cope with deadlines because the real world isn't any nicer (his lover is also an architect).
In addition, several scenes show the students grouped around drafting boards and, at one point, in a fellow student's dorm room as they prepare for their presentations. The conversations do not, as they so often do in Thai dramas, revert entirely to discussions of food and drink. The students have a grounded topic to discuss and debate.
Good writing choice--and an interesting one!
