Dr. Jiang invented a time machine, but a few glitches during its trial run caused it to crack apart and scatter across different places.
Shiguang and Shiyue: Dr. Jiang’s adopted children, fraternal twins.
Shiguang: A soft little puppy, a bit of a chuunibyou.
Shiyue: A cool big sister with exceptional fighting skills, cold on the outside but warm on the inside.
Wu Yu: Her thought process is unlike anyone else’s.
Huo Ting: A funny, lovestruck girl with a sharp tongue, but she’s a great cook.
In short, this is a story about searching for the fragments.
