Why the yuri tag tho? They seem to be very good friends
Not every yuri story has explicit sex, you know.
For the longest time, in manga of every genre, swearing that you will stay forever at somebody's side counts as a declaration of love.
Woah, dude, it was a joke, the meme? "they seem to be very good friends", chill.
The whole story is like... Gaaaaaaay~
