I've recently started playing these games and am very confused on how to properly progress. I do things like send texts to girls and the top right shows the girl's name with a heart +1. However, a lot of times the heart percentage doesn't increase on the phone. There are other times where the character reacts poorly and I still get a plus one heart. Like if I send a girl a flirty text, she will tell me it was inappropriate and not to send it again, but I still get the heart plus one on that.
Also, I feel like some locations are missing. I met the blonde girl at the university and she told me she hangs out at the library. When do I get access to the library?
Sometimes when talking with girls I get a heart increase and sometimes I get a personal happiness increase or decrease. It's confusing on how to progress especially when I can pick the same options two days in a row and have it be good or bad.
I no longer get a heart increase when I complete the chores for the week. Was that bonus supposed to stop?
I bought more than one knowledge book and it won't let me use more than one. Is there a cooldown? The book says using it will use 4 hours, but no time is lost when I use it in the bookstore.
What's the point of the gift book? I give it to a girl, she thanks me, but I don't get a heart bonus for it.
