Tomb Raiding: From the Start, My Cover Was Blown?! Better Make Something Up

[All Male Love Interests, One-Sided Feelings + Villain Protagonist + Feigned Affection, Sincere Hearts Misplaced + Real and Fake Revenge] A quick warning before we begin: the protagonist is a scumbag. He deliberately approaches and seduces everyone, both emotionally and physically, but it’s all for an unspeakable purpose. The pacing is a little fast at first, but will gradually slow down. P.S. Most of the plot is original. Only a few storylines overlap with the original work, so please don’t use the original to criticize anything you think is off. Thank you. A soul who appears to come from another world claims that his enemy is in this one. To get revenge, he plans every move carefully and makes himself the bait, using his looks and acting skills to slowly get close to his enemy’s enemies. But who could have guessed that his identity would be exposed from the start, forcing him to reveal who he really was as soon as he entered the game? But when everyone finally learns that he came from another world, how can you be sure that this, too, wasn’t another way of planning ahead? “What? You want to know what I’m really after?” “I’ve never wanted anything. I only want to survive. Staying alive is my one and only goal.” “Of course, it’s up to you whether you believe me. That’s my answer, and I never lie.” “After all this time together, do you really not feel anything for us?” “I do, but it doesn’t matter.” (What good is sincerity, anyway? His true heart died long ago.)
