(On hold) Can't we go back to the old days?

Yes.. it's a bit of a mess and it might flow differently from the title. Still, please take care of me~ I think I'll cut out a lot of the story after reading the comments for this work~ Hehe~ Actually, I only planned the first half~ (I'm doing it for fun) Sorry, the story is long~ Please look at it favorably even if it's boring~
