I think I can understand what's going on, so since the senior confessed to the MC that's what caused the brother to run away and die. So time resets and a look alike of the MC appears and stops that same scene from happening by invading their study session, stopping the confession. Hoping this'll have a good ending and story from now !!
So liking fiction is disgusting now? It's like saying liking murder documentaries or horror movies will make you into a future serial killer or something. And it doesn't look like the kid is inlove with the teacher at this age too, and they'll be together when the kids an adult and smart enough already, they also have the same exact age gap as my neighbours so calm down yall
Holy this is intriguing
