oops that follow was on accident, its just my guess but i think the grandma might be a fake? maybe to keep minchan from getting suspicious about his own identity. Since it was mentioned that his soul was split into 10 parts, perhaps he continued living until now but his memory keeps on getting erased by that black haired guy? (i forgot his name)
But apart from all that, who puts a grandma in a closet ???
