After Breakup, My System Made Me Rise

Kane works a summer job to buy Anna a new phone after breaking hers, then goes to the Institute of Technology to give it to her. His ex, Mary, mistakes him for a simp and publicly humiliates him for waiting tables and being from a different social class. But giving Anna the phone activates Kane's Rebate System. He receives a limited-edition phone, $10,000 in cash, and an acceptance letter, having ranked first in the university's hardest major, paleontology. His comeback has only begun. He's assigned to live in an apartment for female students, where the system binds him to Anna and her two roommates.
