Well that research tree is very interesting and a little bit complicated, But thanks to my favourite YouTube user Mastermax888 i manage to get some great insights on this and i am taking some notes 📝 so far he hinted on how to free chiku and fexa so far but he has some info on Frenni past but he has not mentioned anything about when to tell her about her past yet so I am keeping an eye on his YouTube channel to learn more on how to free Frenni but i have a feeling that night 9 won’t be the night to free her but i will keep a open mind for this.
