Friendly Rivalry - Season 1

A set of elite academy practice questions sent by someone-they're exactly the same as today's surprise math quiz at school. Drawn in as if by a spell, Seul-gi heads to Elite Academy. There, she runs into Jae-i. But... can she really trust Jae-i?

Jae-i gives Seul-gi a new school uniform as a gift. Though she was once wary of Jae-i, Seul-gi begins to lower her guard as she sees unexpected sides of her. She makes up her mind to return to the seat next to Jae-i.

After the class president election, Seul-gi grows closer to Jae-i and ends up spending the night at her house, but when she's woken by Jae-i's phone buzzing nonstop and decides to check it, she's hit with a shocking revelation.

A copy of Seul-gi's essay, the only one to receive an A+, is found in her classmates' desks, and while Jae-i gets upset and insists no one read it, Seul-gi, strangely enough, doesn't seem to mind.

Disappointed to learn that Jae-i had an ulterior motive for getting close to her, Seul-gi finds herself nearing midterms. With her medication running out and no prescription available, she turns to illegal means to get more.
