Her reputation is what determines the ending, if I'm not wrong. She can perform public favors during the day, which severely lowers her reputation among the students in Hogwarts. From this point on, you can summon Hermione for favors during the day or night. I recommend making her stand for 1 point, it keeps Gryffindor's points from catching up so quickly. You can only see this scene once so I suggest creating a savepoint here to see all of them. She agree to any of them, but only if you give an appropriate amount of points for the act you can't really fail or make her mad here so choose whatever.

This is your first 'favor', you have 4 options to choose from. At some point, Hermione will ask you for a favor in exchange for points.

I suggest waiting it out since you can't access favors yet. Either wait it out or use gifts to calm her down. If you choose to tutor her, she'll get mad you won't teach her. You can choose to tutor her, but Akabur is a lazy fuck so he didn't put in this tutoring mechanic. Eventually, Hermione will ask you to tutor her. Continue to search the cupboard, write reports in the morning, hang with Snape at night. This means she won't perform any favors you can either wait it out or use gifts to calm her down. Whenever you try to do something she is unwilling to, she will leave and get mad at you for a few days. You can buy fiction books, but you can't really do much with it just yet. You can buy educational books to increase your report writing speed and book reading speed. You'll soon find Dahr's Catalogue in the cupboard to buy stuff. Your new schedule will be search the cupboard, write a report in the morning, chill with Snape in the evening. It takes 7 chapters per report and you can submit a max of 6 reports for 200g per payday. You can start writing reports to earn gold.

Eventually, the Ministry of Magic will send you a letter about sending reports. Continue to rummage the cupboard, nap, then hang with Snape. After a while, you and Snape can start hanging out at night. Your daily schedule will now be rummage the cupboard, nap 'till nightfall. After the fight, you can hang out with Snape at night. For the fight, just defend whenever the magic circle appears or Snape starts his casting animation. When you find receive potions from the cabinet, you'll get in a fight with Snape. Remember to do this daily for free items/gold. Next day, you can start searching Dumbledore's cabinet. Explore the room and it'll turn to nightfall.
