What the hell is wrong with her?! She’s has BAD commitment issues

She doesn't understand why Lee Hwa left her. She never understood it, and it traumatized her deeply. She spends most of her time with Seo Woo trying to enjoy the closeness and affection, but she's afraid to think of the future, because her relationship with Lee Hwa taught her that believing in a future together is just asking for pain, because that relationship ended suddenly and without warning.
What's more, since she doesn't understand why it happened, she's afraid that it's her fault, and so she spends a significant amount of time worrying about doing or saying the wrong thing and driving Seo Woo away. That's why she tries so desperately to be placative and to avoid anything that could lead to a fight, because she never understood why Lee Hwa left her. She thinks she was too clingy.
She thinks about that ALL THE TIME. "I shouldn't be so clingy" "She'll get tired of me"
What the hell!!!!?? It was just getting fantastic!!!
