Loved the cover ideas. Especially that they are numbered: 1-2-3-4-5-6
The author was planning to continue with this for 6 volumes, lolol. After 6 volumes, Ayaka was supposed to still be in love with Hiroko and Hiroko was supposed to still be oblivious.
I don't think I could have taken it.
Thank goodness it ended in 3 volumes!
They're just cover sketches and probably all done working on cover for vol 1. Something combination of 3 and 6 were used for vol 1, 5 was used for vol 2 and none match vol 3. Do like how recognizable the characters are even from some rough sketches.
