Chara never left your side. They were always there to give you a hug, or hang out. Best of all, your parents, Asgore and Toriel (not following the StoryShift timeline, I only took Chara), were okay with it, since they feel guilty for always being inactive in the house. Always work to blame.

Fun Story About Chara: You caught them once sneaking glances at a girl in your highschool (mostly humans, monsters are the staff). It was obvious that it was love at first sight.

You get a knock on your door, and you recognize who it is.
