MTL - Shoujo Grand Summoning - ~ 002 Crystal Palace system is the true face!

The dawn era after the end of the half century has gradually rebuilt the order, abandoned civilization, and is full of undivided violence and desire.
The noble and powerful pioneers are in charge of the city, and the evil and mad plagues are in the wilderness.
Pure human beings who cannot mutate are the weakest, dominated by the rulers of the pioneers, and are not as good as animals in the wilderness.
A purely humanized young man with a worldly experience has quietly entered the WTO, holding a three-foot long knife and a long-distance desire to boil in the world of purgatory. From the nameless name to the sorrow of the Supreme Court, the name of the black ride is resounding!

- Description from Uukanshu (translated)

[Adapted into Manhwa]In a world teetering on the brink of annihilation at the hands of the primordial evil, Erebos, five heroes rose to challenge fate. [The Brave] Arion. [The Divine Blacksmith] Dweno. [The Nebula’s Progenitor] Luna. [The King of Wisdom] Lisinas. And finally, me, [The Hero of Beginnings] Kyle.After my reincarnation, I found myself hailed as a great hero. “Except for one small detail, nobody mentions me.”At the Hero Academy, where the sacred gift bestowed by the gods, the Hero Record, chronicles the deeds of legends, I enrolled to uncover the truth behind my forgotten legacy.“Fine, then. I’ll just go there and become the top student. No big deal.”

“I hope you don’t fall in love with me, because I won’t be taking responsibility,” warned the young man. “Don’t worry, I won’t fall in love with a body double,” the employer dully replied. Yet, both of them forgot what they had said.

“Sometimes it's about remembering and never forgiving.”Jane Devold, the only daughter of the CEO of one of the most successful tech companies in the country, grew up to be a seemingly happy and spoiled young woman, despite her stuttering and fragile condition.However, her rich and elegant way of living ends in a heartbeat when her father goes missing, leaving Jane alone and with an enormous debt on her hands.That's when she reunites with Vernon Lin, her strange and intimidating senior from college, who claims to be the new owner of her father's company and promises to resolve her financial issues if she agrees to marry him.His offer seems harmless, and Jane accepts his helping hand only to realize that Vernon's intentions are not so pure, and his personality is still miles away from that of a knight in shining armor.But what really does feed Vernon's unhealthy obsession with Jane? Whether it's his desire for revenge, his own twisted way of teaching the spoiled young woman how the real life works, or unresolved complicated feelings, he still succeeds in turning Jane's life into a living hell.Until he realizes that without her, his own life is hell, too.
