[Two male leads, pairing with Gin, protagonist on the Black Organization's side, Infinite Flow + forum, happy ending]
As an utterly ordinary low-level member of the organization, Baiye Xunyi died during a mission.
After his death, he came back to life, reborn two weeks before that mission.
Baiye Xunyi: Heaven hasn't forsaken me! This time, I'll definitely avoid dying!
But on his second run, Baiye Xunyi dodged the fatal bullet, only to be hit in the heart by a second one. When he opened his eyes again, he was back two weeks before the mission.
Baiye Xunyi: Is heaven messing with me?
Baiye Xunyi tried again and again, only to discover that he couldn't avoid his inevitable death. Just as he was about to give up, a forum called [The Grim Reaper's Elementary School Student] suddenly appeared on his phone.
Only then did Baiye Xunyi realize that he was an NPC in an anime, a passerby whose name and face never even appeared in the actual show. His fate was to die on a mission two weeks later, an ending that couldn't be changed.
Baiye Xunyi was furious. Did being an NPC mean he had to sit around and wait to die? No way.
So Baiye Xunyi began desperately searching for a way to survive, and in the end, he really did find one.
He just had to cling to Gin's coattails. If he became one of Gin's subordinates and rose to become a core member like Vodka, he could rank up to an important character in the anime.
Looks like the only way to stay alive is to win Gin over.
