Shino has been the protagonist's childhood friend since they were kids. She is like a symbol of a man's "preferences"... A girl with such high specs that anyone would take a second glance if they passed her by. However, everyday life with her doesn't seem to be just peaceful.
Good NTR game. Best selling point is that there are 3 quality heroines, your childhood friend, her older sister, and their mom. It took me 8.5 hours to see all the routes and endings except for the happy one. The negative reviews seem to be because some people found the game to be "aimless" or have "no sense of direction" but I didn't find that to be...
