The hole in the wall is initially impossibly small, since it had cinched up around the girl's waist, despite her head and shoulders actually being larger in diameter than the hole itself. She had no tools present, so did she just ram her head through the wall? If the temporary door material is sturdy enough to cause possible lacerations on her waist, she likely would have gotten a concussion bashing herself into it. Why are so many calling this chapter "amazing"? It was pointless filler with no story progression other than this girl is an annoying stalker. Honestly, MC should have just draped a blanket over her head and called it a day.
