- Description from Uukanshu

Veyne came from the life of sewer rats.The world saw him as a failure. He called it belief. Others called it stupidity. Either way, it was the only thing he had left.Even at rock bottom, Veyne never stopped believing in himself.Betrayed by his lover and brother, treated as a burden, and forced to slave endlessly in the game to chase his dream—he endured it all.Though late, his obsession was finally rewarded with an opportunity. But the sewer rat in him was too weak to hold onto it. He had fought the world and lost.Actions have consequences. And when he failed in the game, those consequences caught up to him, leading to his death.But the universe wasn’t done with him yet.Given a second chance, he returned to a time when the game had already been out for two years. This time, he rushed to obtain the Template Wilder class—the very class that led to his downfall.One of the game’s rarest hidden classes, the Wilder class, allowed him to switch into different forms based on the monster templates he possessed. An overpowered ability—but it came with a fatal catch.A hidden template forced him into the form of an ancient baby creature, one so cursed that players, monsters, and even NPCs would hunt him down. If he died in that form, his character would be permanently deleted.In his past life, he underestimated the class’s dangers. And the world tore him apart for it.This time, it wouldn’t be just hollow belief.This time, he’s not here to survive—he’s here to dominate.No emotional ties.No second chances.The entire game is his enemy, and he will crush anyone who stands in his way.He failed once. He suffered. He died. He was erased.Not this time.This is the beginning of his legend. The era of Veyne Draven.

agreed. He thought they might just talk, have a few drinks, and that nothing significant would happen. However, she invited him to a hotel, and they spent the night together.The next morning, she told him it was just a one-night stand and that they would probably never meet again. She said goodbye and left. Ronan also decided to treat it like that.The next day, at his college's hosting club, Ronan was given the responsibility of hosting that year's annual function, where they had invited a singer.When Ronan looked up at the singer, he was shocked—it was the same woman he had spent the night with. After checking her history and social media, he formed an impression of her. Every picture she posted was in revealing clothes, bikinis, or almost nude outfits.He concluded that she was just a promiscuous woman, likely driven by lust, and that she had probably chosen to spend the night with him simply because she found him handsome.Understanding this, Ronan decided to focus on his work. That morning, she had made it clear that it was just a one-night stand and nothing more. He would treat it exactly that way and carry out his responsibilities.Protagonist has System---No NTRIt's Harem, with many girls but The Singer is Main Heroine.
