Need help finding story. Its euther korean or chinese. Cant remember.

So, its set in the future, zombie apocalypse, the remaining humans go underground. It starts out with the cadets of the plots military force needing rescuing. Then an elite unit of super humans saves them, kinda. One recruit(MC) is super genius level smart and ends up attached to the unit. The ML takes an interest in him and drags him along for missions and lowkey has the hots for him? Anyone know? I lost track of it on my list and niw cant find it😭
