Im not sure if im stuck or its maxxed out but im stuck at 6 pink ish purple hearts and every time the percentage gets to 100 it just goes back to 0 am i missing anything or is 6 the most you can get?
That percentage is sister's lust level--
first you have to get red heart - trust lvl, talk and play with her. Only when you have red heart it can be turn into purple - lust lvl
yea I have all the hearts at purple and they won't go up or down they've just stayed at 6 purple
