Who will you trust? One day, you go hiking with your boyfriend and your best friend. It's already evening, and it's raining heavily.

1. Suppose your boyfriend doesn't love you very much, then he may go to shelter from the rain and won't go outside to find you;

2. Suppose your boyfriend loves you very much, then your boyfriend can't go to shelter from the rain by himself, and must be looking for you outside;

3. The girlfriend said that your boyfriend died at the foot of the mountain. Girlfriend went to the foot of the mountain and said she saw your boyfriend's body:

A. If your best friend is a ghost, you can judge that your boyfriend doesn't love you and is still alive. Your boyfriend won't hurt you. Your best friend is lying, so you need to go into the cave.

B. If your boyfriend is a ghost, then your boyfriend loves you very much. He went to find you and fell off a cliff and died, so he told you to go to the cave to take shelter from the rain. He wouldn't hurt you, so he chose to take shelter from the rain.

So whether your boyfriend is a person or a ghost, you should go in to take shelter from the rain, because it won't hurt you.
