Tokyo: Starting with a fake boyfriend

Osamu Shiratori is reborn in a parallel world in Tokyo. He only awakens his past life memories at the age of eighteen. His high school grades are terrible; he is a perennial bottom-of-the-class super-bad student.
Just then, the well-behaved and academically excellent class monitor came to him, offering a huge sum of money to have him play himself as her bad boyfriend and accompany her home to upset her father.
Several options then appeared before him.
[Option 1: Go through the motions, act according to the script written by Minami Yamabuki, and pretend to be her blond boyfriend to accompany her home.]
Option 2: Go all out and, through negotiation, propose to put on a full-fledged performance.
[Option 3: It's none of my business, I'll continue studying "C Programming Language from Beginner to Expert"]
[Option 4: Taking advantage of the situation, class monitor, you don't want your parents to get divorced either, do you?]
