Hello! beta tester here! to answer your question:
Spoiler alert!
Unfortunately in this game all Love İnterests have their own inner monster side and filling those bars means you get into danger point where that monster can be awakened: but dont worry! ıf you want to survive you need to first see which bar usually moves slowest for each Love interest: for İsaac lust is the bar that skyrockets immediately but he is rather more patient against lure. to survive him you need to carefully put your options and make sure you have right social skill (which you can get once you gather 5 points from logic, power, empathy aspects) each skill can put you out of that certain danger as they reduce as a part of that filled bar when you use the skill to convince characters to stay sane
to prevent lust attack: you need empathy skill
to prevent rage/anger attack: you need power skill
to prevent lure attack: you need logic skill
but beware! each skill will consume your energy and you can only use your skills once (which means ıf you used your logic skill you cant use it for second time).
This means in each survival event you need to calculate your moves and use your skills to survive. and dont worry of dying! certain person has got your back in bad ends and you can always rollback or use ''back'' button to redo your choices though ı also suggest you to save before important events ıf you want to explore all choices you can pick.
