Beta's Life Extension Contract

After traveling through time, Su Wanning had a countdown on his palm: 60 days. The only way to stay alive is to hang out with that iceberg archeology professor. She thought she was gathering wool. Unexpectedly, the professor was also waiting for her to take the bait. "There's no point in holding hands." "Um, so?" "... In a different way." (Later, he thought every day: Why is she a Beta? Why can't she be marked?)
