It is a happy one. Just remember the manga is not grounded in reality anyway when you consider that there is a bird with human-like intelligence. So basically anything isn't possible.
*is not isn't
Thanks for your response.
I'm a proofreader so excuse me for being a nerd.
It's not (is not isn't). If you want to use double negative form to confirm the statement, it's verb + double negative. So you can say (anything is possible or anything isn't impossible or nothing is impossible). The latter two are double negative forms while the first one is positive form.
lol no problem! Ty! (●'◡'●)ノ
Can someone who read the raws please tell me if this story is happy ending or sad ending? Did main characters got together? I don't want to be spoiled but I just saw the tragedy tag and couldn't bear breaking my heart.
