@SugarArirang It should have been a Shounen with Romance, Shoujo is just purely love and romance stuffs.
Hmmmmm but yeah other sources said it's Seinen or Josei too, quite ridiculous.
@Pwarghle I guess it's the same as Kagerou Days. They will keep repeating the day as they stuck in a loop where they are trying to save each other.
You guys should go watch the Kagerou Days PV, it's something similar to this.
@zeldashaircut dude why not? the stairs could be slippery or her hand could be sweaty, either case it's totally possible if you slip your hand out of no where :)
