15 parts Ongoing MatureJae-hyun Kim has the grades, the pedigree, and the perfect girlfriend. On paper, he's exactly who a graduate student and GTA should be. But perfection is fragile-and when Amanda's choices drag him into the orbit of Justin Caspian, another GTA with fists trained for the UFC, Jae's carefully ordered life begins to splinter.
What starts as a debt turns into late nights far from the classroom: bruises, discipline, and lessons that feel more like challenges than favors. Justin is everything Jae claims to despise-direct, relentless, impossible to ignore. And the more Jae resists, the more he feels the ground shifting beneath him.
Caught between the comfort of Amanda and the pull of Justin, Jae tells himself he knows who he is, who he loves, what he wants. But denial has a price-and the closer he gets to Justin, the harder it becomes to keep his lies straight.
In the classroom, in the cage, and in his own chest, Jae is learning that some fights don't wait for the bell.
And the one he's running from might be the one he's already lost.
