Coaxing or sweet-talking? That wasn't something that he did.
Especially not to his fans.
However… He could try that with Yiling… Jian Yumin tried to imagine Jian Yiling pouting at him. It was an incredibly cute image. And thus, he came to the conclusion that it was probably worth a try.
The other members of his group continued to encourage him:
"It doesn't matter whether or not you have this skill. The important thing here is coaxing your sister. But then again, now that I think about it, your sister is probably quite good-looking, right? After all, with your appearance, I'd assume that good looks run in the family."
"Hmm… Brother Yumin, why don't you invite us over to your house for a day? Let us see your sister!"
"Yeah, I like that suggestion as well! Let's all go to Brother Yumin's house."
