**[Status: Remaining lifespan 29 days 17 hours 32 minutes]**After reincarnating into a modern fantasy novel he had read in his previous life and enduring all sorts of hardships, Ryu Seo-ha awakens as a precious S-class healer. However, he also sees in his status window that he has less than a month left to live. Then, after an unexpected encounter with Choi Gang-hu, the protagonist of the original novel, Seo-ha discovers that physical contact with Gang-hu increases his magical power. And Gang-hu begins to show a peculiar interest in Seo-ha.“Do you intend to repay me?”“Yes.”“With your body.”[Preview]As Ryu Seo-ha was leaving the bathroom to contact the Awakened Management Bureau, he stumbled back in surprise. Choi Gang-hu was leaning against the entrance wall.“Why are you here…”As he hastily stepped back and stumbled, Gang-hu grabbed his arm to steady him.[Magic Power 9]At that moment, Seo-ha’s magic power stat began to skyrocket.[Magic Power 17] [Magic Power 25] [Magic Power 33]The numbers increased dramatically with each blink of an eye. It was an impossible situation. Seo-ha’s eyes widened in shock. Gang-hu also seemed to sense the anomaly, raising his handsome eyebrows high.For some unknown reason, a chill ran down his spine. Reflexively, he shook off the hand holding his arm, and the feeling of every cell being filled to the brim suddenly stopped. Feeling dizzy, Seo-ha shakily leaned against the wall for support.[Magic Power 41]In that short time, his magic power stat had surpassed 40. This was a level that could only be barely achieved by investing all stat points gained up to level 40 into magic power. It was an astounding situation.Gang-hu, looking down at him with eyes as dark as an abyss, didn’t seem to have intentionally infused him with magic power. There was no reason for him to do so, and it was impossible for the stat itself to increase like this. Even if it were just an increase in magic power capacity, it would be enough to make him a research subject.“I thought I was imagining things,” Gang-hu muttered in a low voice as he slowly reached out his hand again. His long fingers lightly touched Seo-ha’s pale cheek. As he shrank his neck at the cool sensation, Gang-hu’s large hand cupped his entire cheek.

In an inaccessible village, there were a few houses on the hillside.

People from far away were attracted here and the mountain road was crowded with luxury cars, because, in this town, there was a young man with incredible medical skills who could cure all kinds of illnesses!

- Description from Novelupdates

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?
