Herroine has no friend / betrayed by friend / bullied by friend

It's me again hehe. I always look for something great to watch when I'm stressed out. About the topic, I only know Bleak Night (korean movie), I am about to watch it later or tomorrow. I don't like cheesy show, like obviously targeted to younger teenagers. *Sorry*

Thanks. I do prefer something where you can feel their closeness or friendship first, and not immediately get bullied or was left by his or her friend hehe
