On the 4/10/22 Inbou released the patch for the game with 4 routes completed (Yuuna, Miyabi, Tonoko, Shino). The 2 routes that are missing (Misaki, Sumika) are not planned to be translated since they tried to hire staff to do it, but no volunteers ever pulled through with it. As it stands, the project is done and released at 4 routes total.

Patch can be obtained here:
