I am a boy. My senior and I are in a school where no one is there. What did she want to do after hugging me all morning?

First, it depends on your age. If you are a senior, there will be senior in primary school, middle school and university. Those above high school can be over 20 years old. When you are an adult, sticking to it all morning may be a good feeling or a good feeling for you, which proves that you like you very much. This is also a way of falling in love. She is very active, so don't miss it if you think it's appropriate. Better for her, too.
