I'm reading Hoshizora no Memoria right now. I finished Asuho, Komomo, Kosame, Aoi, and I feel like I'm near the end of Chinami. I'm really excited to read mystery girl and Mare's route. So far I'v liked all the routes with the exception of Aoi, who was painfully annoying for 3/4 of the route. I can't get enough of Okaizumi's shiiiiiiiiitt and Komomo's reaction, it cracks me up every single time.
Since the sequel isn't translated in English yet, I'm going to try it with a Chinese patch. I'm not fluent but I studied it for 4 years so hopefully it's easy enough to read to still be enjoyable.
