After Xiao Hanyue, Ye Yunqi, and Lin Ling finished watching the commotion caused by Ye Yu, they went to the small lounge where Ye Ningsuan was resting.
Earlier, both Ye Fei and Ye Ningsuan had gone in together, and they had all seen something inside, but nothing seemed amiss at that moment. However, when Ye Fei came out but Ye Ningsuan didn't, it raised some suspicions. So, they decided to go and check on her.
Fully contented, Ye Ningsuan had actually fallen asleep after Ye Fei left. She only woke up upon hearing Ye Yunqi and the others knocking at the door.
When she realized that Xiao Hanyue had also come along, she was afraid that Xiao Hanyue, being experienced, might detect some peculiar scent in the room.
So, she deliberately delayed by dawdling before finally opening the door for them. She then made up an excuse about feeling unwell, further delaying their return.
