A young man gets picked up by a System still in training, then tumbles through all sorts of romance novels for girls as an anonymous passerby.
Gu Huan thought he would spend his whole life rolling around in romance novels for girls. Then one day, he received the wonderful news that the System was upgrading.
The conversation went like this:
System: Chirp... System update. Upgrade available. You can now switch worlds.
Gu Huan: !!!! Switch worlds!!!
System: Chirp... Player, would you like to upgrade the world?
Gu Huan: Yes! (At last... at last, my time has come! My mature ladies, my lolis, my sweet little girls are waiting for me, along with my countless underlings. Here I come!)
And so, Gu Huan was brought by the System to a danmei world, where he went through all kinds of cannon-fodder training, endlessly repeating his tragic history of getting pinned down... and taken from behind.
(Gu Huan: Damn it! Where are my underlings and lolis?!
System: Chirp... Player, could you stop derailing the plot all the time? You're clearly cannon fodder.)
System: "Chirp... Player... this is a danmei story..."
Idiot: "Damn it! Shut up!"
System: "And... and the player is... cannon fodder. How can you take the protagonist's route?"
Idiot: "What the hell! Do you think I want to get my ass blown out like this?!"
System: "Chirp... as... long as the player follows the guide, everything will be fine."
Idiot: "Damn it... I've been following the guide this whole time, and that's why I keep getting my ass blown out!"
