Guysss!!! I think the old man is the first chapter is mitsuhara, because look at his hand if he was shinpei the ring on his pinky finger that satoko made for both of them would be there, as well as scars on his arm, we all know he has a lot of scars on his body, so my pov is both satoko and shinpei had an ending together ╥﹏╥ (I hope)
