- Description from Novelupdates

In a world governed by the mysterious power of dimensional gates, young Dabi, once frail but gifted with a photographic memory, discovers his life-altering ability: a leveling system that grants him new skills and magic as he rises through the ranks. After his family perished in a gate-related tragedy, Dabi swears to protect his siblings and unravel the mysteries within these deadly portals. Alongside his loyal spirit pets and rare allies, Dabi faces ancient threats and powerful enemies tied to his parents’ tragic past. As he rises in power, Dabi’s quest draws the attention of noble families, dangerous royals, and sinister forces seeking control over dimensions and the future of humanity itself. Secrets, betrayals, and a growing vendetta lead him deeper into a battle that threatens the fabric of existence. With the fate of his world hanging in the balance, Dabi must outwit and outfight forces beyond imagination all while confronting the truths hidden within the gates of the lost dimension.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…

“VILLIAN!? Is that what you call me? Do you know what I have been through?

FATE dealt me this hand, and I'll find peace in it. Even if I have to end the world, I'll sit a king on its ruins.

I'm not a good guy. I won't even pretend that I am. But then again, who in this world can truly claim that title?

At least I know my heart. What about yours?”

Chiron lived an unfortunate life, but his problems only got started when he was reincarnated in his dangerous Hit novel.
