There's hope yet! Even with the open ending I feel that it's quite fitting, I thought it'll be too weird for Sho and Jun (and Nino and Aiba) to be able to be together with the restriction on both of their worlds put on them when Ohno just offer them the chance. It's up to Sho and Aiba to take it. and I think that will take up entirely new chapters (if you gonna write it, in which I'm not sure if you are XD)
All in all, this is a great chapter. How bittersweet that lovemaking is? I thought I'm going to cry with the beauty of that part.
So Jun's (as well as Satoshi and Mao's) mother was a collector too, no wonder Satoshi is too overprotective of his siblings and try not use collector anymore (but of course Jun is as stubborn as its get)

Thank you again for writing this wonderful fantasy story. I love it and I'll miss following it. On to the new journey!
