(Warning: Harem, if you don’t like it, please refrain! Boldly breaking taboo ethical norms, not letting go of any beautiful women encountered!) A young nobleman with a delicate constitution, pure and kind, has always been protected by everyone. However, after two months of military camp life, he began to change for the worse. With unbeatable power in his hands, he became lawless, targeting countless beautiful women in the city. In his eyes, every beautiful woman is like a delicate flower. He wants to gather these tender flowers around him, then extend his strong wings to shield them from any harm...

He became stronger, faster than anyone else… but he lost. In the end, there was only despair for Kim YuWon.

In his last moments, he was given another chance… Through the sacrifice of his comrade, his fate had not been sealed yet.

Returning back to the past, he attempts to climb the Tower again with his unmatched talent.
