This is what I understand for conditions to get each endings
Normal Ending (no sex):
Shizuka able to reach deadline but love below 80 and libido below 40
True Ending:
Shizuka able to reach deadline and love above 80 and libido above 40, on day 5 (night), Shizuka should be at bath and ask you to get cloth, go take cloth and there will be sex at toilet during midnight , then tomorrow go to store to buy condom
Bad Ending:
Shizuka doesn't reach deadline when you don't clean bathroom, toilet and refill energy drink. Doesn't matter what level of love and libido
Dog Ending:
Same as true ending route, but instead of getting cloth, you go to your laptop and then you will try to check Shizuka's pc
