I mean no judge but Sarah kinda lame nothing intriguing about her only she is kinda wild from time to time
Heather seems like a drama queen so i about her down
Heather doesn't instantly fall for the MC like 90% girls in this game. This in itself makes her stand out. And I'd say Maya is much more of a drama queen than her, forcing the entire main cast of BaDIK to constantly shoulder her life problems. Heather has a strong character plus short temper which is an explosive combination, resulting in lots of angry outbursts by her. But this trait, although I agree it might be irritating to some people, also makes her character original and gives potential for interesting relationship dynamics. Outside of that, her looks are among the very best.
Sarah is far from being lame. You may dislike her for her personality, but she is probably the only character outside Quinn in the entire game who is not afraid to speak her mind or trash talk somebody. Even though she sleeps around a lot, she is not a hypocrite about it and doesn't pretend to be somebody else. And she doesn't idiotically fawn over the MC. Even if she loves having sex with him, she doesn't idolize him and tells him what she thinks. She also possesses one of the most realistic body proportions and normal face, thus doesn't look like a doll (like many character models in BaDIK).
