if im not mistaken, she got overwhelmed and stressed, everyone got into uni, and i think at that time she was stressed alot, and she broke up with him, but she expected they will get back together but he didn’t try to persuade her or anything, they just, broke up like that
It was over the stress and she was embarrassed of herself. She planned to get together after she got into the uni but she couldn't and got more embarrassed so she NVR asked to get together. On the other hand jaehyun thought they will get together after she gets over her stress so he gave her some space but she kept on ignoring him.
did i forget or they didn't reveal it yet?
