What Happen to Jhin

Ok he was bullied by his friend from the academy mostly from Ekko and Ahri because he was to slow. So he made a gun ,but since his dad was a weapons builder for Garen and some other people, his dad disaproved it. He kept updating it , everyone laughed at him, and some said "Ha, Nice Gun haha I have magic LOSER" - Vladmire. He was very sad and mad ,but then he found a friend named Amumu. They shared many memories together ,but when the "Man" was choosing people ,well I'm not sure because I haven't been chosen, he picked Amumu. So Jhin and Amumu part ways, without Amumu, Jhin was lost and all he could do is build his gun. Overtime he got obsessed with perfection, he wanted to make the perfect gun ,and soon he met Jinx. He fell into the crimes of Jinx ,but unlike Jinx he was clean, no one knew who he was ,but he never shed a finger print. When he did, he almost suicided, he needed to be perfect. Then the annual "Choosing" came by ,and everyone was excited. Then 5 names came up, "OK, who is it going to be?" said the unknown man "EKKO!!.........Who is next!........Tahm Kench!!.........Then.........Kindred!!!............IIIaoi!!.......Last but not least Jhin....." -The Man said. A few years later Jhin came out, he was different and looked dead, he also walked like a dead man some others came out like Amumu,Little Gnar,and some others. What happened to them .Hmmmmmmmmmmmmm
