Thread Colors ~Sayonara no Mukougawa~

Childhood friends and new mates are met in high school and the town hospital when the main character of the game interacts with four teenage girls and a leggy guidance counselor. As the game begins, the player wakes up at a hospital with memory loss and struggles to remember a life lived and friendships from the past. The game takes place primarily at the hospital and the local high school where the girls drift in and out of the player's daily life. During the hospital stay, our hero befriends a girl who tends to be sickly and naïve to the ways of the world but perhaps the two will help each other recover from their respective ailments.
