Why to get relationship points with the other dudes? I dont see anything changes if I get them high.
Probably if you are trying to see bad ends.
Also jfc, $50+ energy drinks and condoms? What kind of fucking economy are they working with?
Btw, is there a more in-depth 'MC end' rather than just managing to have sex with her in the third position (doggy style) and suddenly winning the game? The game seemed like a race to win her affections first since no matter what you did, her enslavement and relations with others keeps going up, but I see that NG+ gives you an option pay 10k to reduce her relations with the others which seems kind of pointless since you can just buy condoms and end the game sooner. Makes me think maybe there's a time-gated ending, but I haven't tried yet.
Also, what exactly does her mood do? Seems like your mood affects when you get great results at work, but what does it change for her?
