kuudere is best dere, then tsun
yandere is nice in 2D but the one you described doesn't sound like she'd really love you if she tries to manipulate you for her needs... however, I don't think you'd have trouble finding a girl like that
this one girl would always spam me with messages and it was very obnoxious, she was quite needy and said she'd kill herself if i didn't go out with her. it was extremely stressful because at the time she was my best friend
i wouldn't wish that kind of psycho on somebody else
