My older sister hates me and our parents for something other people did to her.

I (20M) am a White man living in the US East Coast. I live with my White biological parents, and I have one sibling, an older adopted ethnically South Korean sister who I usually affectionately call Angie (31F). Before the events that are described in this post, my sister used to love me, and when I was little she swung me around in her arms. Up until recently, she's never had a problem with being adopted by a White family.

Many of my male friends have crushes on Angie. Indeed, she is conventionally attractive, and she looks like a really elegant (my mom calls her "regal") anime girl. She's got really long black hair and thick bangs. A few years ago, I bought her a beautiful red headband which she always wears and always loves. She looks totally feminine, but she's actually a complete tomboy. She loves sports, and has played basketball in college. Even nowadays, she goes running every day. Also, most of her friends are guys.

The events that I described here happened partially because my sister knows she's conventionally attractive, and she always very confidently, unnecessarily flaunts it.

This past August, my sister and her fiance (27m) and two my of my male friends (both 19 years old at the time) took me to a cottage for a week. They basically live right by that cottage. It was really nice, really big and cozy and it had a full bathroom with a shower and everything. My 20th birthday happened during that week, and we celebrated. The day after my 20th, things went horribly wrong. Early that day, Angie's boyfriend had to stay shut in his room because of some personal emergency. So to distract me and my friends, my sister took us outside, and we spent the afternoon at a table playing board games (my sister is REALLY into board games). It was a hot, humid day, so Angie was wearing nothing but a bikini top and basketball shorts, without her red headband (her headband is so precious to her that she didn't bring it to the cottage).

It was a living * for her. My friends couldn't shut up about her shirtless body. She started out taking it quietly and without emotion, but it took just minutes to get her to start crying. She spent an hour and 45 minutes, just sitting down at the table crying quietly and sweating heavily nonstop, and she kept her shoulder glued right onto me and her sweat drenched my shirt. She also kept her arms tightly crossed over her chest the entire time and I believe she was terrified that they were going to touch her breasts. But all they did physically did to her was yank her ponytail at one point. When my friends started joking about a "struggle snuggle", it made Angie openly loudly bawl. At that point I grabbed her arm and tried getting us away from them, to the woods where I could be alone with her, but she couldn't stand on her own legs, so I put my arms around her body and carried her to a lonely area to have a heart-to-heart moment with her. When I picked her up (which was difficult because she's much taller than me), she tried to scream but she could only make this quiet whimpering noise. It was so awkward.

Nowadays, my sister is still not doing well. She's legit traumatized by my friends. She hates me, and she hates my parents too for some reason (they didn't do anything to her and they love her. They're heartbroken that she hates them).

I mentioned my sister's race because she has let me and our parents know multiple times that she wishes our parents hadn't adopted her in the first place, because maybe then she wouldn't have been put through this situation.

Nowadays I just really miss the times where my sister used to pick me up and swing me around in her arms without a care in the world. When she says she wishes she weren't adopted, she's saying she's willing to give up those memories.

Despite all this, she still wears that damn red headband I bought for her. Sometimes I feel so angry at her that I just want to rip it off her head.
