Poison reciding inside (Gyujin)

Falling from a 6 story bulding was definitely not a plan he had for a sunday morning, but he also didn't plan for what was following after that. Ending up in a familiar yet not so familiar environment made him question whether he was or wasn't plummeting down 50 meters from a hospital a few seconds ago. Reality seemed to morph into something much more complex. The present turned into the future meanwhile the past became the present. Jumping back in time was even more surprising to Yujin than his best friend and at the same time closest family member going behind his back. He never thought losing his friends and lover to the future would hurt him so badly. Knowing that most of them weren't even acquainted with him yet, he decided to pursue a quiet life. But the visions of his future wouldn't leave him alone, making him try to save his loved one from unlucky incidents that he foresaw. Because one thing that nobody ever knew was that Yujin had been able to see into the future from a very young age. Yet with that there came a condition, the first time he got hurt was also the first time he saw something from the future and that has continued to be so. Every time he suffered from some kind of pain, he caught a glimpse of the future...But now it has been happening more frequently, even when he wasn't hurt. And it was all about the same person???
