I have thought about this a long time ago, if I set the protagonist in the ending to be the imagination of everyone who has come into contact with her, it may be more attractive. Is it full of drama for a person who never really existed to be filled with various emotions? Of course, this is just my idea. In the end, I gave her an identity, or more accurately, an origin. The so-called protagonist still has to have a reasonable way to exist. Haha, I don't deny that even so, the existence of this character is quite unreasonable.
Intention: life, love, self and others.
