Basically satomi decides to let kyouji go and kyouji lets him even though it's implied the decision wasn't what they both really wanted. They go their separate ways but they both look back as they part without the other knowing :((( there are many interpretations like maybe there'll be a sequel, that maybe it is best for Satomi to let go for now but that kyouji will wait until he's ready..... yeah

Someone spoil me please, I tried searching on twitter but I only got old chapters …. How does it end ?
