thats the only one i could think of that ressembles your descrition
it's not this one sadly but thank you for trying!
Hello! Gonna drop this ask and hope beyond hope someone might know this one. I've read it years ago.
I remember reading a manga about a boy (high schooler most likely) who I think wears glasses who's transported to late 1800s early 1900s Japan (there might have been early models of cars) and he finds himself living the life of one of his relatives or something (forgot who exactly but it's a grandpa or someone from that period he's seen in pictures and whom he resembles). I think there's another boy that has light hair in it but I'm not sure.
All I remember is that it was about a love that never bore fruit because of the times.
I know it's vague and my searches have been in vain and I've been looking for it for years.
