Crime Scene -

Her friend said she wouldn't, but maybe she's wrong.

No, I don't think she did. I think she had too much self importance going on for that.
There isn't much information to go on for now but I am wondering if Mee-Yon isn't gay. Her bio said that between school and work, she doesn't have time for a boyfriend, yet she spends her free time with Courtney. Even Justin says she's always there. They always planned to go to school together and most people who do that, choose to share a dorm room but Courtney got an apartment that someone else pays for and Mee-Yon doesn't know anything about him/her? A real best friend would know something. Could Mee-Yon be that jealous of Courtney? First a boyfriend, then an apartment and now a baby? As I said, not much to go on but I would watch that one.

My gut doesn't like Kim for the murder, but you've got a good working theory there.

I think suicide is a possibility, but I want to wait for autopsy to give us some info on the damage to her face. If it's fresh, it pretty much rules out suicide. Could even turn out to be C.O.D. though strangulation is obviously more likely.

I'm really thinking that the damage to her face was because somebody hit her and knocked her out and then hung her. Or, as you said it could be the COD and the hanging was just to cover it up and make everyone think she committed suicide.
