With a Game System in the World of Conan

On the eve of Valentine's Day, a couple queued up to play a game together, then somehow wound up in the world of Detective Conan.

"What? It'll take twenty years to repair the space-time tunnel?!"

Zhang Jing and Li Liang, wearing secret identities provided by their dumbass System, tearfully go further and further down the road of crime (not really)...

This story includes cases adapted from real life and the author's chuunibyou fantasies. It does not follow the manga and anime completely.
