As long as you have Fumi as an Ally you can win, just call her for help and she'll have a whole Swat team to help you. You can also say you have a secret to tell them and if you are doing the play through correct you'll scare them into telling you where Dorian is. (Never waste money here, just ain't worth the trouble.)

@Axeman, ty I was having trouble with the cassie part, do you know if the 200k is required for cassie or is it equal to just calling the police?

[Motivation 25] You can do it Cali! I believe you!
(Secret picture found in the clouds near middle of the screen)

[Suave 40 or Buff 18] (Both options don't add hearts but you decide what stat you need, Suave is my choice since you need a amount of it in the third week and above)
[Any option works] (You shouldn't have any points in the black, if you do at any time than you have messed up the playthrough)
[Buff 21] I could beat the shorts off you both. No competition.
[Suave 50] How about a kiss?
(Whatever you do, do not be romantic (or rude) with Cassie, this will ruin your chances of getting the A+, the stat ups are not worth it, neither will you gain points with cassie (You should be maxed with her anyway)
Cassie, retract the claws.These are my friends.
Busy at the moment. But I'll be in touch
Bye Cassie
Nothing serious (You shouldn't have any points in the black, if you do at any time than you have messed up the playthrough)
I, too, have to pee. Race horses couldn't even understand my pain
Oh hey, you're not homeless!

(Crack a beer and wait) (Ok I think you get the message of not having any black karma)
(Sing along)
(Question) Been a while? Getting some, I mean?
Don't worry. You never forget how. It's like riding a village bicycle.
(Question) Well, what's the deal with you and Cali? I think she likes you...
I get the feeling she'd upgrade again in a heartbeat.
(Question) So, you're having a dry spell,hey? No wonder you're so cranky all the time...
[Buff 27] They you got a look at this hot bod.
Cheers!
[Buff 30] How else am I going to prove I got the goods?
Well... It's been a while for me too, and my first choice.... Is not interested.
[Suave 30] Someone sounds... A little jealous... (If you flirted with Cassie you would get a different dialogue and not get an A+)
It made an Impression (3rd Secret optained)
[Any choice]
[Buff 33] (Break her grip and pick her up.)
Yes... (If you say anyhting else then smack yourself)

Here is a preview for the guide, just because I want you to A+ Iro's date.

Man that's impressive! I was looking at other dates too and [Iro 3] has defeated me - I am like 1 pixel away from A+, I am wholeheartedly expecting someone to tell me I have made 1 wrong decision but I swear I've explored like every path

Oh yeah, I'm making a guide right now that has every date A+ with hints, secret pics and optimal actions if people want. I'm almost done with quills A+ section and then all i have to do is the side dates and rush through the game and write down the best choices while making sure the guide is correct. Trying to get it out by tomorrow.

and also WOW I can't believe that "this has been weird" is in fact the key, I knew about the "warm feelings" thing but that other one I just didn't expect

Wait really @AxeMan you've A+'d everything?
