Demon King: Me and Me

Don't look forward, which means don't be anxious or panic, and don't lose or forget. But after losing his beloved, in order to revive her, his anxiety, panic, loss, and forgetfulness were all described in his body. When he experienced the destruction of the seven worlds, he discovered that his true love was the transformation of the resentment of the world, just to let him taste the pain of loss forever. When he understood the truth, he found that he was the devil in his destiny.
