Translation error will be in next update.
As for the walkthrough, I'm assuming you only changed/added to Julia's part? In the way you are doing it, I have no way of knowing exacly what you are adding and fixing. (I'm trying my best to updating the somewhat "official version"
here)
A little change by Yana to make clear to use anal lube then finger her and then you can fuck her ass. Stand before lube and fuck her ass when you go only after the hint you fuck her ass and she don`t like it (no anal sex anymore) so I add this information.
Before drug dealer and mom small infos.
Julia I don`t have the orginal walkthrough anymore only my changed. In the old they wunder how you can raise the stats without cheating (the stats should raise when you deny her money and this is complete wrong) and I wrote after you have had the first time sex then the stats from her raise before they don`t. Small infos for Julia. I don`t know if they are only so or if they are for the future. Maybe you must do aso something other to unlock it I don`t know.
For example I haven`t proved to pay the dress for Julia then you get the answer you feeled betrayed if this change anything other then. When you go out with Julia you are in the museum and she talked to you it is to expensive she can`t demand it as a gift. So I haven`t tried out to pay for the dress and look if this options change.
I delete/change the walkthrough so the points 5-7 all other are from the other walkthrough. You pay the 100.000 when you don`t have the money that you can pay her later. That you must spend money to her at her home to 120.000 and after that at home you need 250.000 for the dress and deny it (I haven`t checked it what you can do when you spend the money if options changed).
In the old walkthrough was don`t give money to her. So this was changed or was not correct.
I haven`t checked if you buy the dress the only different is that you must pay 300.000 then.
You must spend money to her first (120.000) talk in the livingroom and only after this she visit your home to demand the 250.000 for the dress.
For example small info. Julia came home drunk at 9:00 hour and Dinner in the kitchen I see at the moment no improvement that you can trigger a improvement scene or that this unlocked another scene. Grocceries buy at midday when you do it you have sex.
If you say that you need the info or not you must know yourself I think it is helpful for the future to check if he changed there something.
At the moment I try to play all on the love route. I haven`t played all girls free or to the end so I don`t know if I improve a little the walkthrough. Aso if I have bugs or not that means that a option is blocked only from another girl.
For example in the new year I can buy all stuff again I haven`t checked this closer. Was this a special day and when I play this year aso to the end is the same next year aso and so on. Normal all stuff you buyed before and is in the inventory is blocked to buy again.
Future
The school close days I want to write in the walkthrough that you know at which time you can try the girls in the school time again. So you can try all other girls you don`t have at this time.
