(((This is only 1 out of many different ways to go.)))
Make a save and then do each one of the convo's with the npc and once you find out what they don't like you asking for now leave that for later. (You should figured out what to do and what not to do as you go.)
Once you have given them all the gifts they ask for you should be able to get there phone number and just start calling them every day many times a day.
((After the second gift start asking them for there phone number.))
That slut that is on the PTA took me a week to get her phone number and after that it was smooth sailing to get in her pants.
I've tried that already dude, with calling and everything they all hate me because of the drugs and Hypno and keep asking about their hobbies, I did that thing with save before but it's quite annoying because it takes a while to load.
For the PTA Detective, i asked her what's her hobbies and she says "I'm not interested in nothing" so i talk about politics and she replied with looking embarrassed for myself, the anything part about this it is that idk if that's a good thing or not because after hundreds of trying with different NPCs as well the only 2 texts I got is that with embarrassed and "That's not me but thank you"
See how broke this is? with 0 indications from the game idk if i did something right or wrong. (The big one doesn't contain that stuff as well trust me, I checked. that's how i learn that everything i was doing got my NPCs loyalty/relation lower)
The game is really fun and i enjoy it but man... it's described very wrong, I think I'm gonna deleted for now and wait for V1.9.6 hoping for a more decent conversation system.
And I need to leave a true review of what people really get in
