Park Sumin, has always been the girl on top-number one in everything, from academics to ambition. Her name was a constant on every first-place list, and nothing seemed able to shake her perfect streak. That is, until the unthinkable happened-she slipped to second place.
The new top spot belongs to Kim Eunsoo, a quiet yet brilliant, whose unexpected rise shakes Sumin's world. As if that wasn't enough, Kang Yerin, a cool and composed, starts climbing to third place, threatening the comfort of Sumin's former glory.
To make matters worse, betrayal brews beneath the surface. Sumin's so-called friends have turned their backs on her-framing her, trashing her name, and pushing her further down.
What begins as rivalry soon evolves into something more complicated. Tension, secrets, and buried emotions weave a story where competition slowly gives way to unexpected connection. As chaos unfolds, something unexpected blooms between the top three-something deeper than rivalry.
As Hanni's thirst for success grows, so too does her willingness to bend the rules, to cut corners and manipulate her way to the top. When she challenges Professor Kim with a smirk and a daring question, a dangerous game is set in motion, where the line between teacher and student blurs and the stakes couldn't be higher.
