I've been wanting to ask this question for a pretty long time towards my readers who have been reading my Mafiatale series, seeing as it's something I've debated about on and off again. 

As you can tell I do like to include more ships than just Frans into the story, just so there's more going on, and it's fun to have other moments with the other characters and because I don't always like rushing through Sans and Frisk's story, (and admittedly, sometimes only writing about them and no one else can feel a little dull for me from time to time). Not because I don't enjoy it but because sometimes I do wanna include the other characters.

But anyway, I'm getting off track here.

I wanted to ask: how do people view Chara and Asriel's relationship? Because the thing is, obviously they aren't biological brother and sister, and personally, at least for me, I see them seeing it as them being really best friends, rather than siblings, because Chara isn't really Asriel's brother, you know?

But putting Charsriel (or whatever their ship name is) into the story has probably been the ship I've been the most nervous about, just because I question whether people see them as brother and sister, best friends or what. I just worry about losing reader's interest because either they're just not interested in the ship or for some other reason they might think it's weird.

But over all, I just want to ask: is this a couple you would like to see in the story, or do you just prefer them being only friends or family?
