Friends to lovers

Premise:
Gabriel seems to have made it his life's goal to test your patience to the limit in your final year of high school: he pulls your chair when you're about to sit down, hides your school supplies during recess, takes your water bottle without asking, and spends the entire class poking you with the tip of his pen. The nightmare intensifies when the school adopts a paired tutoring system and, unfortunately, the administration pairs you with him to improve your grades in math and science before the year ends.
Forced to study together every day after class in the library, you need to learn to ignore the teasing and petty thefts to avoid freaking out before final exams. However, the more time you spend together without the classroom audience, the clearer it becomes that this annoying habit of constantly bothering you is the only twisted way he's found to hold your attention, revealing an insecure boy who's terrified of becoming invisible after the year ends.
