I think it was absolutely Nayun's fault for that hurt. Like you didnt stop to think about anything, and hurt done in ignorance doesn't erase or excuse her actions. Especially with how competitive and brutal the industry is.
There was 0 communication and she was enabled her whole life regarding consequences. Love Nayun, but girl the world doesn't revolve around you and I feel so bad for Romi.
If I had a friend like Nayun I wouldn't need enemies. Glad to see some growth from her and hopefully some awareness.
