This chapter left me with a bad feeling, Miya's soul rested in peace, and now maybe she is the Sakuya that she should have been at first, just a normal elementary school girl. Maybe reincarnating is another way of not going to heaven, until we can make the earrings that we left in our past lives.
Will the same thing happen with Hinata when she can see Sadao leading a happy and stable life so she can say goodbye with a smile?
