The HD remake of Hatoful Boyfriend: A School of Hope and White Wings seems to have save issues when a save point is generated during certain portions of the game.
If you're playing the Steam version of the game, this thread on the Steam forums may be of some use to you. The issue also occurs on the DRM-free version of the game as well as I recently came across it in my copy of the game. Apparently, the save feature glitches up most often if the player tries to save right after a scene transition. The now-broken save file will only load the background and the character if loaded from the title screen or load everything but the text if loaded while playing. Either way, the menu cannot be accessed on the broken save so you have no choice but to close the game and restart it.
So far, there's no solution to salvage a broken save file so the only choice as of now is to simply start over and replace the broken save.
