Struggling 20-something Tessa has a dead-end job as a barista and the dream of a creative career that never quite seems to take off. When the coffee shop where she works goes out of business, she's able to visit her parents for the first time in years. Arriving at her family home, she discovers that her parents have rented out the basement apartment to her high school nemesis, Olive Virtue. Old wounds resurface during Tessa's stay, but an accident that traps them in the attic forces them to face their past and think about their future.

I Hated You in High School is an enemies-to-lovers story inspired by classic romantic movies--with a queer twist. Author and illustrator Kathleen Gros has expanded her short story webcomic into a beautiful tale of love and learning.
