After learning about the things that happened in this world Valdel could not decide what was the right thing to do. He had come into this world expecting to come and go as quickly as possible. He was expecting an entirely different scenario to transpire, he wasn't expecting that his resolve would break so easily.
In the end, Valdel decided to stay in this world for a few more days. Seeing as Silika did say a second in the world is a day in this world, so Valdel had a lot of time to think. He wanted to see what kind of world Lisa was living in.
...
It has been a few days since Valdel arrived in this dream world. During this time he couldn't find the right timing to have another conversation with Lisa about this being a fake world. There was also the problem that for every day that passes in this world, bits of his memories about the real world were starting to fade. There were still there but they were becoming slightly blurry.
