How about #4 and 5 with Daison, Junomo, and Prakaa?
4. How easy is it to earn their trust?
For Prakaa, it's fairly easy to earn her trust, she's very welcoming to new people just as long as you're sharing good vibes with her.
As for J and Daison you might need to dig deeper. J's only really trusts a group of people she keeps close, they're all people she knows will always have her back and Daison just claims he does not trust anyone, period. Realistically though, being genuine with them or showing interest in their work will at least earn Daison's respect.
5. How easy is it to earn their mistrust?
The easiest way to make J distrust you is by insulting anyone she considers close. She values her relationships even if she's a bit awkward to show it.
For Daison, he's naturally suspicious of a lot of people due to his line of work but once you've earned his trust, you're basically set.
Prakaa does not like being lied to. She's a bit of a pushover in the sense of forgiveness, but if she catches on to you lying to her without clear reason, she will genuinely get upset.
