A manhwa that tells the story of Allen's revenge, the chosen hero who was abandoned after defeating the demon king. Sick and unable to cure his illness in any way, he asks the goddess who granted him his power to return to the past so he can take his revenge.
With such a strong revenge plot, we go back to before everything happened, a moment when Allen had not yet been chosen as a hero. He will use everything he knows about the world to fulfill his revenge in the most particular and perverse way possible.
Characters of The hero is disappointed
Allen
Our protagonist, the hero chosen by the goddess to defeat the demon king. He uses all the vitality that his powers as a hero give him, both in battles and in bed, consummating his revenge.

Santa Marian Delarossi
The saint who accompanied the hero and the one who went looking for him to check that someone who would save them from the demon king had really appeared. In her previous journey, she did not try to heal the hero even once despite being a saint.

Sacred Knight, Genoa Darius
She is the sacred knight, the strongest and the commander of all knights. She also didn't try to help our protagonist even once. She was also the first to flee when she had the opportunity when they were facing the demon king.

Karen Cruz
She is a mage who was only with the hero to experiment on his immortal body. More than helping, she creates problems for our protagonist and is the one who set traps for him while he fought against the hordes of the demon king.

Opinion of The hero is disappointed
A revenge story that has more than one reason to be, where each member of the hero's team is basically worse than the previous one. A revenge story where our protagonist, upon seeing the true faces of his companions, will not fall into their traps again.
The protagonist doesn’t mince words and with great impetus gives a quite interesting plot to the story where literally it feels that nothing can stand against him after obtaining his hero powers.
