Oh my b. Wow, learning that there are 5 more chapters cranked my anxiety up to a 100. A lot can happen in 5 chapters.
I feel you. The story could have ended in this chapter, or in the next one, with Maki and Midori running away together and living happily ever after. But if there are still five, count 'em, FIVE more chapters, it means that the author intends to deal exhaustively with all plot lines and characters, and tie up any loose ends before the conclusion.
So yeah, a lot can happen, both good and bad. Buckle up, everyone, this will be a wild ride!
