I'm starting to realize why people are dropping this. We are at 49 chapters and no real progress has been made. He still just stares at her, fully aware of his feelings, and his thoughts of this situation are only ever kept thoughts. I mean like in chapter 48, the last full chapter before this, he was just perving and thinking "Hehe what if I catch her in a compromising position where she's near naked?" It doesn't feel like romance, because he is fully aware that the things that she does so casually are inappropriate, and things she should definitely be careful not to do, but says absolutely nothing because he enjoys seeing it. "She's so defenseless" Brother you sound like a creep.
It was somewhat cute at first but we're 49 chapters deep and its just the same deal over and over, it slowly losing its charm and becoming weird. The art is absolutely great but the story is just not really hitting.
