Getting transmigrated into your favorite game sounds great… until you spawn in a high-level boss dungeon with a dead party at your feet. After suffering a fatal heart attack, one hardcore gamer wakes up to this exact scenario. Desperate to avoid a second death, he convinces the dungeon’s boss that he is the monster’s long-lost son. The lie miraculously works, but now he must endure grueling training under the terrifying Demon King. He wants nothing more than to escape, but surviving his “father's” brutal methods might be the real challenge. Will he ever make it out alive?
