lurker's Questions (2)

So the story is about mc who goes back in time somehow to when he was a high schooler as a closet gay but had a thing for his friend and his friend also had a thing for him. When he goes back in time, he decides to just date his friend? but like in the present time before he time traveled, they weren’t in contact anymore? Also in high school they were in the track club I think but then mc got an injury or something and couldn’t run properly anymore so he stopped going to practice?

Sorry for vague description (￣∇￣")

I read it on here but now i can't seem to find it and i don't remember the title. I swear i put in in my reading list but maybe i didnt. I think it was by the author of Stalker's Game too. Anyways, the manhwa is about mc who was always second to ml in highschool and thats all i know really lol. There were only like 2 chapters out or so. I read the raws and from what i could get from it, mc is like a writer and ml is a painter(?) post high school. Mc wanted to get back at ml and tried to blackmail him by recording them having sex and from there they kind of became sex buddies? Idk lol.
