Having reached his talent limit on magic, the protagonist was sent to the gaming world as punishment — to a huge city named Valkan. In order to survive, he builds relationships with other people and investigates the secret behind the “closed world”, striving to prevent the end of the world.

Earth ends up in a worldwide death game where everyone from the ages of 15 to 29 must participate. In this 20-round death game, Ryu Min stands alone at the entrance of the last round. However, the game taunts him, killing him for having not met the entry requirement of a minimum 5-man party. Now, on his 100th and final attempt, he uses the information he learned from his previous 99 attempts to help raise the necessary companions to reach the end. Can Ryu Min finally beat the game, or will he perish in his attempt?

Only music sustained me from the maddening pain. If only I could hear my music... with my own ears... Even as my soul was falling apart, I prayed to God... and prayed again. Ludwig van Beethoven is considered the greatest composer in human history. I closed my eyes like that. And 180 years later in Seoul. The saint of music, known as an immortal genius, has been reborn. And then I began to hear the voice of an angel. "Dobin.. Dobin.." Only music sustained me from the maddening pain.

Do Ahyeon is a total nutjob, at least according to her boss, Heeseong. Not only is she blackmailing him into sleeping with her for fun, but she's got a phone full of guys she's ready to get down and dirty with at a moment's notice. Sharing is caring in Ahyeon's world, and there's more than enough of her to go around. But while wading through her diverse cast of boy toys, from total players to absolute control freaks, Heeseong begins to realize that he has real feelings for Ahyeon. And now, he won't settle for being second... or third, or even fourth best. It's a love-hate relationship of the most complicated kind, but he's willing to do whatever it takes to win this wily woman's heart.
