Yumi kept staring at Erich throughout the night... It was abundantly clear to everyone at the table that something was going on between the two of them. In this life, Erich had been exceptionally careful to disguise his intentions towards alien women. That was a reputation that followed him until the end of his past life. One that had many negative consequences.
Having learned this lesson, Erich had taken things exceptionally slowly with S'aleth, and had gone out of his way to bury any evidence that might have existed about his one-night stand with Yumi. But Yumi never forgot about Erich. In fact, she had become even more obsessed with the man in this life.
After all, his accomplishments were far superior in this new lease on life, or at least what he had officially achieved during the few years he had been able to live since returning to his 18th year. Thus, Yumi was quite flirtatious with Erich, coming on stronger than made him feel comfortable.
