I'm afraid the diary is still quite broken, I've tried to fix it but I haven't been able to do it, so I'm going to look for help to make it work for the next update.

So even though it says fail is there still any progression to be made? The diary bug occurred after the new park scene you added. Is that it for the update? or was there another scene apart from that with rina?
edit1: decided to grind up all the stats for rina to 40 and that progressed to the h scene. Diary is busted but at least the 3 heart stats works fine. if you feel like there isn't anything to do in the game because it says fail or that's all for this version just grind it to 40. Normally i would consider this a spoiler but i stopped playing for like a week because i thought i burned through all the current content
