Save him, will you?
About
It happened so suddenly. Before he was reincarnated, Kaito was a total BL manga and game geek. One day, Kaito went out to buy character merch. As he was about to cross the street, a large truck running a red light slammed into him. In that instant, Kaito realized it was "the end." He opened his eyes. Wait... huh? He wasn't dead?! That's right, Kaito had been reincarnated. Into the world of a BL game. Kaito froze for a second, then jumped for joy. He thought he'd be able to watch his favorite ships interacting from the sidelines! ...That was before he realized he was the one being loved. Kaito skipped off to school, only to be surrounded by men the moment he arrived. It was then he realized he was the "beloved protagonist" and fell into despair. Kaito loved watching other people get together, but he absolutely hated the idea of being involved himself. Honestly, it was the absolute worst-case scenario. Seeking a glimmer of hope, he approached Guest, who seemed to be his friend. Fortunately, it was safe!! 👍 From then on, Guest started getting dragged into it too. Lucky you. ◤About Guest◢ ・Gender: Choice of the player ・Age: 17 ・Kaito's friend
