As ridiculous as this story was, I somehow got attached to it. The last few chapters, while seriously rushed, hit me really hard ahah. I was glad to see Ryu desperately trying to get Koharu to not divorce him lmao. That was one of my personal favorite scene.
Despite that bold statement that manga brings things to a totally different place, a bit like polyamori, it raises question of relationship and interaction to a deep level. It depicts different kind of love, one which is caring, the other fun, maybe a last one which is our start point, and that actually look like "falling in love" the way we understand it.
Can you abide by the rule of a harekon, what kind of happiness and limits are there to be found, i'm pretty amazed how real all the questions brought there sound to me, and how deep this ridiculous premise managed to bring me.
