I checked your save file.
Everything is good in your save file and you have progressed well in the game.
As I said, only you need to know what the next step is at every opportunity.
To do this, you can use the in-game hints:
In each stage of the game, the next step will be shown to you as a hint. Note the following photo:
If you know what the next step is according to Hint but you did not know how to do it, you can get help from the game guide and read the section related to the same opportunity in the game guide. See next photo:
If you tried your best but still failed. Ask a question about that problem here, I'm sure I or other friends will help you.
For example about Alex , yes you have to talk to Lisa about Alex.
Or you should talk to Lisa about what happened in the morning and apologize to her.
Also, as I mentioned before, in order to make the game easier, I suggest you stop checking the effect of Max on the girls. Just focus on this and use all the opportunities to improve Max's relationship with the girls.
