Who is Madeline again?
the MC's bestfriend in the orphanage that she always remembers
Omg lol it could be. But somehow it doesn't click, maybe the Shinsu did possess Madeline & befriend MC at some point hmm （￣へ￣）sounds possible… or not (?)

Madeleine might be a villain or antagonist soon. Judging that she is always mentioned every now and then, I bet that she will be a main character soon.
Shinsu is Madeline, I think.
