ST:
Love the story but this thing needs some *MAJOR* Editing & overhaul (small wonder so confusing!)  
Example:  Tasks say:  "Her living place"  (complete BS!)  but *ACTUALLY* it's  *YOUR*  Extra  (listed as "Alternative" in Tasks)  (RENTED) room.  
*HER*  LIVING PLACE in actually in *TOWN*,  & finally figured out,  (far as I know)  there's *NO* 0  nada scenes there!
Even makes hints & those who give them way extra complicated!  (&/or confusing) 
If she's in a room that's  *NOT* yours  (eg,  sisters/"girl's room"/default single bed)  most scene's aren't possible.  (far as i know so far) 
Instead of "Drained"  or "your relation is too depraved"  (WTF?!?  BOTH of those seem to mean the SAME THING! ie,  "no longer helps")  it *SHOULD* say:  Have done  x/8 times.   (like  3/8 or   [done times/  MAX possible times])   FYI foreign (or even ENGLISH) devs,  MATH & #'s R universal,  & should be used whenever possible for best clarity.  [even "no longer effective"  would help some (default is "still effective")---but *NUMBERS*  would help the *MOST*!  [one obviously impacts another,  so there's a range?] 
Aunt's schedule should give you *SPECIFICALLY*  (her rely in R/L wouldn't help AT ALL!) what day(s) she's staying overnight.  (you have to rent a room *JUST* for her!)  Dialog makes her sound like it changes every week (?)  but from *TASKS*  there's only *ONE* week which repeats so...   (?)  
Last,  FYI for those doing it,  lists of scenes  don't help if we can't UNLOCK them!   (so we need Req Stats/date/time/etc)  
I'm very hesitant to even try to use cheats w/o an Official  (from dev or coders)  WT----depending on code,  cheats may "break" game so some things no longer work.     [just as some R having problems with] 4 Example,  "interrelated variables."
$ money [oh FYI dev that's *BALANCE*]  is probably ok cheat,  but that doesn't unlock anything.    [crazy story even has *FREE* bus rides * (WTF?!?)  *FREE* LAWYERS!  ]  Seems a lot like Glassix,  everything Time/Day/Location specific.   (+ sex stat?)  
BTW,  GLASSIX  [hint hint dev!]    has place you can lookup  Time/date/place (etc)  Requirements for a girl.  *** Would be *VERY* helpful here! *** 
In reply to last post:  
no, NO (i wish!) simple WT; 
there's some help for their "likes" (convo) but... not really needed can figure it out. 
Tasks R often confusing at best, & at worse, say nothing at all.
