It's best not to promise such a thing. You should know that this boy is a senior and will graduate soon. Can such love last? In fact, you already know in your heart that the other party is insincere and can't be sincere. Don't think everything is beautiful just because you went to college. There is rubbish and love rat in the university. A person, especially a girl, should learn to protect herself, and don't think of each other beautifully just because of a little sweet talk and kindness. Think about why the other person asked you out at night. There must be a purpose. Learn to refuse people yourself. A lot of things are lost and can't be found again.
