Yejun, a history instructor at a cram school, prides himself on professionalism. So when his former best friend, Minhyuk, suddenly appears as his teaching assistant, he keeps his distance. Their friendship ended painfully, and Yejun has no intention of revisiting it. Yet Minhyuk seems determined to pretend nothing happened, smiling and lingering just close enough to unsettle him. Beneath their polite exchanges lie unresolved tension and buried feelings. While teaching their history lessons, they'll also have to rewrite their own past. ⓒ Bareum / KIDARISTUDIO All rights reserved. Published by Tappytoon under license from partners.
