Traveling the Three Thousand Worlds with a Sign-In System

Sign-In System:

The host isn’t very smart, always wants to charge ahead recklessly, is lazy, and a foodie. What to do? Online waiting, quite urgent!

Each world is a standalone unit, with one protagonist per unit. Every world can be viewed independently!

(Important things are repeated three times.)

It can also be understood as each “Qing Yue” from parallel worlds traveling through with the sign-in system. The worlds they encounter and the order of their experiences differ.

Most arcs feature CPs (couples). Some may not, and others may break existing CPs depending on the story’s development.
