"I won't let myself die like this! I'll survive no matter what! And... I'll definitely save her too!" When I woke up, I found myself in the world of the romance RPG Engage Hazard, a game I had played extensively in my previous life. However, the character I had reincarnated into was none other than Harold, the "Vile Prince," known for breaking off his engagement with the heroine and being cowardly and despicable. At this rate, I'll be defeated by the protagonist and executed... First, I need to stop breaking off the engagement with the heroine and use the knowledge from my past life to grow stronger! This newfound determination catches the attention of the heroine and others around him... Can Harold successfully avoid his bad ending?!
