Fair enough.
In order for me to get the first two sex scenes (on bed, and at doorway), I had to do something at exactly 15:00 (first nap, then TV). For example, the first one: the diary says, nap and then wait for her to get back from school. But what it should say is nap exactly before she would return to school, without the waiting. I was under the assumption, at first, that all the sex scenes were going to occur in the bedroom in the same way that I trigured the vag oral... by asking her the question about it. Whereas, the next two lewd scenes are triggered automatically by doing a specific action at a specfic time. So I kept wasting my hard-ground lust points on the same vag oral scene - unaware I was supposed to be saving them, because the events werent occurring. Then I went and started reading the walkthrough. Then I started cheating so I didnt have to grind anymore. I encountered no random events - everything I experienced was triggered by something (either a question, or a specific action at a specifc time).
Regardless, all I was trying to say was that I shouldn't need a walkthrough or cheats to figure it out (the tutorial and diary weren't clear enough to me). It's okay if people want to use a walkthrough or cheats, but I prefer to play games without them. I like the immersive experience A game should be intuitive enough for me to figure it out on my own and not get confused or lost in loops. I've had the game a while now, and only started looking for answers today. Walkthroughs are meant to enhance plays, but not meant to be necessary/dependent.
It's just my opinion. Maybe in the future when it is out of beta, that will be the case.
Anyway, maybe my experience will help other newcomers in the future.
