In the first chapter when I saw the FL standing for her, I thought, Oh this is gonna be a great story. From the second chapter, its just got weird, she doesn't know anything. Okay I know she suffered, but just what she did in those 10 years. She don't even know how to use a phone. In 3rd chapter even though he was nursing her, did he really needed to take off her clothes. What husband wife relationship does he want, after leaving her for 10 years. I can't read this anymore.
In most of this sex friends kind of story, the seme is really arrogant or indifferent. But Koichi seems kind. I think he's actually in love with Kai but can't bring himself to tell him.
Some stories have so many emotions and meaning one can't grasp it just by reading once. And every read gives a new perspective , this story is just like that. I'm feeling a rollercoaster of emotions.
