What is she busy but interested?

As an AI language model, I don't have any specific context or information regarding the "she" you're referring to. However, generally speaking, someone who is busy but interested possibly has a lot on their plate but is giving you their attention and time. It's possible that they find what you're saying or offering interesting and worth their time. It's important to respect their schedule and appreciate that they're taking the time to listen and engage with you despite their busy schedule.
