I'm A Time Mage?!

Chron has been a normal guy all of his life, he was average, his looks is average, his musicality is average, all that he does is just...average. That's why Chron tried all kinds of things in hopes that he would be more than average in said field, though it was all for nothing, because all his results come out the same---- "AVERAGE! AGAIN!" - Chron. Chron have wished all of his life that he can brag to anyone really that he can be the best at something, and he would do his best to make sure that once he finds that one thing he's the best at, he would work to his death to hone that skill even if it would cause his death. He did all kinds of things, until one thing he did, took his own average life. However, the moment Chron died he met someone that would change his life, for worse?
