Notice: This is an idle BL (Boys Love, Male x Male) Visual Novel. (*≧▽≦) This is NOT a dating sim or otome game. It is purely a visual novel with linear storyline.

PLEASE NOTE: This game is only available in the English language.


IMPORTANT: Some Troubleshooting Notes:

- Please reboot your phone if you are stuck on the Unity splashscreen upon first installation, the game should run smoothly after restarting your phone!
- If you are stuck at the Blue loading screen (more than half a minute) right after Unity's splashscreen, your downloaded file may have been corrupted, it would be good to redownload the files if this is the case. To do a proper re-installation you need to uninstall, turn off your phone, wait 7 seconds before turning it back on and then install the game again.
- Please make sure that your phone memory is enough to play the game as low memory may cause it to crash or run with problems.

Thank you for reading!
