I like that line of thinking. It can explain why Naoto was always hurt. When Naoto was first introduced, he was asked if he’s been to the house and he replied as if he didn’t know what he was talking about. Possession is a high possibility. Also the reason why he didn’t remember what happened when they kissed as well.
1. Naoto is Real, just like the mother said he's a shut in, and rarely goes out, but after accident fumiya actually sometimes possess him, thats why sometimes hes wonder around hiura, but he still can't go to him, because he still thinking that hiura is straight, and he already dead, so it pointless to confess.
2. Fumiya really got thrown into the river, but got pick up by a mentally ill woman who searching for his run away son, and make fumiya (that she believes was her son) cannot run away again by drugging him asleep the whole time, and then decided to kill herself and her son (which is unfortunately fumiya in drugged states).
3. Kinda wish sensei didn't give us an open ending, kinda want to know, how naoto feel about this situation, and hows fumiya and hiura relationship will ended (stay as a friend or dating)
