The S-Classes That I Raised

Yoojin is an F-ranker overshadowed by his little brother, an S-ranker. All he does is get in his brother's way, causing trouble wherever he goes. When a seemingly routine dungeon raid goes wrong and costs Yoojin his brother's life, Yoojin decides to use the wish granted by clearing the dungeon to reset his timeline. The plan was to lead a quiet life from now on... but now it turns out he can help other people become S-rankers?! Maybe this is Yoojin's chance at building his own entourage of powerful metahumans... but it may be easier said than done.
