The person below me said that this gal is like Nagatoro if they were a super sadist (say, if she stayed the same as she was in the beginning of that series). She really just likes to make him suffer, and thats what the series revolves around. It got kinda hard to read because I ended up feeling kinda bad for the guy myself, and nothing really changed, its just the idol trying to guilt trip the poor otaku who lives next to her in literally any way possible.
But its not a bad series at all.
The person who does these scans is also really freaking amazing, i'm impressed. Send a donation by his way.
He deserves the support.
