I'm currently playing Tsujidou-san and it is quite enjoyable, yet very average in most things it does. The common route was quite entertaining with its cast and the comedy, but I've been playing Ai's route and it is a mixed bag, with there being some really fun comedy and certain events that I enjoyed, while there also being a lot of romantic filler and boring moments that plague it as well. That being said, I enjoy Maki quite a bit, so I can't wait to read her route. I've also heard good things about Renna's as well, so we'll have to see if it improves or not.
