"Oh right, it's the same this time. We need to find a mystery guest. However, since we are inviting the popular guests from our past episodes for the finale episode, each artiste only needs to find one mystery guest." Lu Dongliu did not mention trying to help Lu Man find a guest.
No matter whom he found, he would not be able to find someone with a reputation comparable to that of either Sun Yiwu or Ji Cheng.
However, Sun Yiwu and Ji Cheng had both attended the show before.
They could come on the show again, but the effect would surely be hugely discounted.
No matter how close they were with Lu Man, they might not be willing to attend the show again.
After all, both of them were big-name directors. If they attended too many of these events, it would easily reduce their prestige.
Furthermore, given Lu Man's sharp wit, she would definitely not overuse Sun Yiwu and Ji Cheng like this.
He just did not know who Lu Man would find this time.
