Pls help to find a manga

I read it a few days ago in mangago. So i can clearly remember the first chapter. But I don't remember the title and pp so I was unable to find it again.

The mc is stalking his crush, who appered as a very kind, charishmatic and inspiring person. The mc started to like him when they were in middle school or something, they were running a race and the mc was a lap behind everyone and his crush tells him still not give up. After that the mc starts changing his style and apperence and becomes very handsome and enters the same highschool as his crush. Note he has nosebleeds when he sees his crush and the mc is probly the same?. Back to the present, One day as usual the mc was stalking his crush and sees his crush helping out a troubled friend by doing his(friend) part of cleaning duty cause of his (friend) request. The mc follows closely as his crush goes into some storage room and bursts out of anger because he had to do the work for his friend. This is not someone who the mc knows his crush as.
