Almost exposed

Having his eyes kept open because Xiao YuYi is still awake, Xiao FengYin wanted to get some water for his sister, but she pulled him back which made him feel more helpless.

By that time, Xiao XiRan and YuYan continued to sneak out and proceed with their plan. They have confidence that Xiao YuYi won't let Xiao FengYin go out of his room.

That night was successful, but because of Xiao YuYi who stayed awake so late, Xiao FengYin didn't get enough sleep. The next morning, he ended up waking up late just like his sister.

There's a bit of suspicion that formed in Xiao FengYin's mind, but this did not stay too long as Xiao YuYi asked something to eat after she expected for her siblings returning to their room.

Starting that night, Xiao YuYi remained staying in Xiao FengYin's bedroom, sleeping beside him with the same way she was on the first night, making her big brother stay up late like her.
