So spoiler maybe, cuz idk how far you have read.. but the MCs body died when that car crashed into him. His soul went into the body of another person who he has never met but coincidentally has the same( last name I think) name as his original body. So MC is in new body, and we can assume that the original owner (red hair) of that body died, original owner(red hair) of that body seems like he was a quiet person that had family issues, maybe would dye his hair different colors to stand out?, ultimately committed suicide and by cutting himself and ended up in the hospital where MC took over his body. ...so MC who is now in red hairs body goes to red hairs school to continue the life red hair was doing, coincidentally again was the same school that MC also had gone too. When MC in red hairs body decides to live as red hair, he dyes his hair black and starts to wear clothing he thinks is more appropriate. People who attended school with red hair get confused of the sudden style change and personality (not shy anymore) he has unknowing that a MC is now occupying that body.
I never felt more confused in a story until now
Maybe it’s my dyslexia kicking in but I don’t get the whole swapping thing I really want to get it because I’m reading all the good reviews <3 can someone dumb it down for me :( who are the two people that swapped, do they know each other? I thought the mc died? Did he come back alive and people are confused he’s alive?! is the red hair the future version of him?!!!! Ahhhh ┗( T﹏T )┛
