I was brother and sister with a friend until yesterday when he went to tell a fortune and was told that he and I were inseparable.

It's no use thinking about some things, just let it be. Neither he nor your friend has exposed himself, which proves that he cares about you as a friend. Just being fooled by the fortune teller, he shook it all out, or the fortune teller gave him that courage. You can't just think that what he did was to achieve that goal. In fact, he may just want to do what he wants. If you think too much, you will harm yourself. If you really haven't had a crush, then refuse it. If you have a crush, you might as well try ~ ~
