I found this sentence on a manga, and I can't find its meaning for I don't understand the function of にも in this case:
For example the question could have been "what are you taking interests in" with "in" standing for に, this would be a suggestion for the answer: "In learning and in sports and also relationships."
In this case you are summing up things you would use に after in a full sentence. 勉強に興味あります。
In this context, 'にも' means 'as well as'
