The interesting thing is that Marie is now stalking a different person from the one in chapter 3, but they ended up being the same person.
Also, Marie reminds me of Makoto from T7S.
@Tcof He was in his apartment all along, the lady was hired by him to pretent to be the author. At this point I think he's just trolling the stalker girl since he seems to be aware of her.
That guy is sleek!
But doesn’t that mean that girl just gave up and started obsessing over another artist...? Too weak willed to be a pure-blooded Stalker
