I usually don't comment about games, but NGDN actually took me for surprise. Sorry if I say something wrong, I am still improving my English.
I really liked the concept to date a NEET girl because there is not too much games or media in general that involves their plot on a character like, in this case, Kara.
I believe this VN has a LOT of potential if Hitsuji wants to expand it. Kara showed a tridimensional personality in just the first date, and the game talks about deep topics that are overlooked in society.
You killed it Hitsuji, looking forward to know more about Kara!
