I'm Just a Supporting Role, an Ordinary Villain.

Just after traveling to the fantasy world, you encounter the marriage of the son of good luck and the daughter of unlucky woman, and you are about to be slapped in the face? Actually taking the blame yourself? Xuan Bei said he was a little confused. Not only was the heroine sent to him personally by her Holy Lord father, but even his ex-fiancée, who had made a three-year contract with the son of destiny, admired him immensely? Tsk, the hatred value of Son of Luck was fully increased at the beginning. This feeling is a bit sour. Isn't it easy to trample to death a little child of luck? Wait, there is a system dedicated to the protagonist? It seems that he wants to go further and further down the road of supporting roles and ordinary villains.
