I, a sophomore, a boy, broke up with my partner because of a short circuit in my brain, but I like her very much. I miss her every day now, but she told me not to.

Pursue her with sincerity. She may just be heartbroken now, but after a while, her heart will soften. As long as you are persistent and kind to her, she will certainly understand, but just be careful and don't make her feel bored. For example, you can send her home or buy her breakfast. I don't think these things will be too much, and it will easily move people in the long run. Don't worry, there is still one and a half years left, and it will definitely succeed.
