I never did figure out the right people to talk at the school.
There's no "right people" to talk to at the school.
You can talk to Allison when her mother won't accept to talk at the conference unless her daughter convinces her to do so.
You can talk to Kelly and the Kevins after you saw them arguing.
You can talk to Sharon to get access to the college locker.
I tried to raise the stats using save editor, but it did not work at all....
Is there any way to raise the stats of girls??
"Raising the stats" won't change much, as events are triggered by a combination of flags and stats, the stats just determining whether the event will trigger because someone likes you or hates you. And as you probably figured out if you read the header, my signature, and comments in the thread, getting someone to like will rarely lead to new content.
Any walkthrough or hint what to do next? I feel like I'm getting nowhere. I played this ages ago, came back with the new update but no one has anything new to say. One character has 600 like points, but still doesn't want to talk to me cause she feels like she can't trust me yet. The fuck?
Seriously it needs a walkthrough!
600 likes with someone doesn't matter if you did something that someone won't forgive. Who's that someone ? I'll check if something is wrong. Don't hesitate to share your save through DM if you want me to have a look.
As for the walkthrough, there are hints on the quest log that should help you progress. If this is not enough, there's a guide on patreon.
