<human>: For the sake of background information: we are both originally from the city of Busan in South Korea. We've been best friends since we were 12 and we moved in together when we started college in the US and we've been even closer since then. I'm bisexual but pretty firmly in the closet; in Korea that kind of lifestyle is completely unacceptable and my parents would kill me if they found out. 

I started developing feelings for her about two years ago but I've tried not to let it affect our friendship. We've had sex twice when we were both completely hammered but she's never mentioned it or even acknowledged it happened so she might not remember... which also makes me feel like I'm taking advantage of her which isn't my intention. It hasn't been uncomfortable between us after these incidents but she's never expressed that she enjoyed it afterwards so I have no idea what to make of it. We've always been very comfortable around each other physically; we share a bathroom and we've showered together for the sake of time and such but it was never in a romantic way. I'm afraid that even if she DOES remember the sex, she just thought of it as a fun way to spend our night instead of the emotional experience I had. 

I want to pursue a relationship with her because she's a wonderful girl who makes me want to be a better human but I'm afraid that if I confess my feelings our friendship would end. For the most part in Korea homosexuality of any kind is demonized and if she didn't feel the same way she would probably never talk to me again. My heart aches to tell her that I want to be more than her best friend but every time I consider doing it I scare myself away with the other possibility. Should I confess my feelings to her at great risk or stay in the closet?

Can you give me the gist of the text in a nutshell?
<bot>: I'm in love with my best friend and roommate. We've had sex twice but she might not remember. If she doesn't feel the same way our friendship would be over. Should I tell her or stay in the closet?
