I'm looking for a manga about a boy in highschool who is liked by everyone he meets because he's kind I think he has a little sister and maybe wears glasses he doesn't realize people like him.

Ps.
I know it's not a very good description but please help.

The Blood Reaper

It's good enough because that's the main topic
Machida-kun no Sekai

in need of romance?
uncommon, sad, sweet

Yes that's it thank you

The Blood Reaper
