“What should I do with your tantrums? I’m too busy right now to be by your side.” Well, since entering the dungeon, I hadn’t really paid proper attention to Cha Sahyeon due to being occupied with various things. It was a golden opportunity to make my face known by Kwon Taehyeok and Ryu Seonghyeon, the targets of the main quest, not to mention the unexpected participation of the Ronic Guild in the raid. Cha Sahyeon seemed to have caught my playful murmurs as his shoulders trembled. Eventually, I heard his subdued voice: “…Don’t go.” “What?” Leaning against my shoulder, Cha Sahyeon stared at me intensely. “Don’t go.” “…!” For a moment, a strange light seemed to flicker in Cha Sahyeon’s green eyes directed at me. Simultaneously, a loud notification sound echoed around us.

An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

I was betrayed in my first life.A cripple, broken and discarded—I died after catching the one I loved in bed with the only person I ever called a friend.That was the start of real torment.When I woke up, it was in another world.A goddess stood before me.She told me I could go back.Back to my world.Back to everything I lost.All I had to do… was play my part.The side character.And I did.I followed the script.Played my role to perfection.They hated me.Mocked me.Used me.Again and again.But I kept going. Because I believed her.Because I wanted to go home.Then one day, I found out.The hard way.It was all a lie.There was no going back.There never was.She used me.Again.Just like everyone else.Thrown away like trash once I outlived my usefulness.That was the day something inside me snapped.And so, I made a vow.I would take everything from her.I would enslave every single heroine she chose.And I would kill the hero she placed all her hopes on.If she wanted to protect this world…Then I would burn it down.But the more I tried, the more things started to change.And then one day—I found one of the heroines.One of the hero's yanderes I had enslaved.She stood there, trembling, a knife in her hand.“You’re not going anywhere,” she whispered, eyes wild.“I won’t let them have you. You belong to me.”...What. The. Fuck. Is. Happening?!
