Day Zero - Make it Up to You

A genius, sorta-kinda high-school dropout rich kid gets Kousuke as a chauffeur for a week for a school project, and things develop differently than expected.

Note: As Kousuke hasn't expressed attraction to men as of now within I Love Yoo, I've made the reader female.

[I guess for a timeframe this is a year after the events of the webtoon? Yeon-Gi and Shin-Ae are in a relationship, and Kousuke has gone back to avoiding Meg and his mother at all costs]
