aww Kazuma and Midori have a daughter! always knew that the love she had for Tsukasa is just
Not It. she was tied down to their past, and she thought she still loved him when the 'real Tsukasa' came back, and he was at his low point that it probably made her think that she had to take care of him. It was almost like an obligation and she was disillusioned by her past love. She wasn't considering those moments when Kazuma simply appeared in her vision even when he was not physically there, of those moments Kazuma simply brought her comfort by simply being there. They had also the best dynamics, they could become each other's lovers and bestfriends at the same time. Their love is also healthy compared to her toxic relationship with Tsukasa.
though, i may be 3 years late, but i must agree with
@jak they focused too much on Tsukasa, should've focused more on a great character like Kazuma. there is so much potential to create more fluff between him and Midori
