Strong BL vibes

It's a sad story :(

It's painly obvious the two main characters are attracted to each other. Seeing as this is shounen ai, I have a feeling they will end up together

The story is really beautiful but it has a bittersweet ending I literally cried when I reached the end :')
It's about a boy who resembles his grandfather goes back in time and meets another boy who mistakes him as his grandfather whom he's had a crush with

I added this to the list because I'm not really sure if this is BL or not... sure there's a kissing scene between boys, but...

Of course we can't skip this manga
Most people ship FrauxTeito or MikagexTeito for this one XD
