Plans
Everyone was completely fine with not knowing Shen Yu's origin, as they were already grateful he showed his past to them. After all, he had basically laid himself open with all of his secrets out.
It showed how much he loved and treasures them. That was enough for them, as they themselves knew they wouldn't have been able to do the same.
Not to mention he was just hiding those secrets because of their safety.
Since Nancy had already said that they couldn't talk about their origin, others didn't pester on them. They just invited Nancy and began to talk with her.
Initially, they were also nervous as it was the first time they were talking with someone so powerful, but as they conversed more, they realised how fun she was.
Nancy's nervousness also skipped away as she took turns to start topic and talk about them. It was the first time she was talking with someone else other than her host and she was enjoying it.
