It's not as detailed as I'd like it to be but it's the best resource on the game out there.
Some personal tips:
Do not have sex with multiple girls or at least not the ones in the same harem (home harem, office harem, band harem, etc) until they have atleast 75 love point (LP), 25 kink point (kp), and 45 (or lower) lesbian point. Otherwise you will lose girl(s) to showdown events. If you do have sex with multiple girls in 7 days, either from events or you fucking up. Avoid the girl(s) or the harem location (such as studio for band harem and office for office harem) for 7 days. For home harem (Bree and Sasha), you can't avoid your home, so work on each of them 1 at a time.
The fastest way to earn KP is by bringing them to pub dates. There are two activities, pool and darts, where if you win (and I assume it's stat based) the girl gains +2 KP per activity, netting you +4 KP per date. If you also gift them "A sex slave's story" for +1 KP (and - 1 or 2 LP), that's +5 KP per day/date not including KP gain from other sources.
It is inevitable that you will make mistakes (I messed up the band harem, causing Kleio and Anna to leave, and pick the wrong choice locking Minami's KP to 50). So it's a good idea to save before doing something on the story tracker, that way you can backtrack without losing much progress. Or live with the consequences until NG+.
