The Academy's Has Too Many Cheats

After downloading the new DLC for one of my favourite games, I somehow transmigrated as an extra in its world. While scared out of my wits at first since the game was known to be extremely tragic with even the best possible endings tasting bitter-sweet. I eventually found some confidence in surviving this cruel world. After all, I knew everything that could happen and what choices each character would make, Once I enrolled into the Academy everything should go my way. But... The main character had regressed. The main love interest turned out to be the reincarnation of the Immortal Emperor. The Holy Kingdom summoned a Hero from another world. A 3rd Rate Villain somehow signed a contract with a Mythic Item. ...Isn't that way too many cheat characters?
