Bound to My Name, Doomed by My Brush

I am the Hogan family's long-lost biological son, while Jared Hogan is the impostor who grew up in my place.

Then, Jared unexpectedly acquires an "Academic Leech System".

All he has to do is enter someone's name, and whenever he takes an exam, their score becomes his.

He mistakes me for the other Riley Hogan, the STEM prodigy who has dominated Elmland High's district rankings for three straight years, and eagerly locks the system onto my name.

With three months left before the college entrance exams, Jared spends every class scrolling through videos and every break playing games.
