(BOYS' LOVE)
When Tai Yang, a young, handsome yet introverted scientist gets hauled into one of the alternate Universes (by a dog-eared man claiming that staying on Earth would kill him), four things become especially clear.
One: his black belt in karate is useless against the strange, magical, anime-looking spells of the alternate world. Two: he needs to stop getting lured into human birdcages even if there is 4-ply toilet paper in them. Three, Prince Li Jun is an asshole on Earth and in the alternate universe too! 
Desperately trying to return to his world, Tai Yang manages to escape several times. The problem? He keeps bringing the annoying Prince back to Earth with him where another Li Jun already exists! And after a while, it seems Prince Li Jun has gotten too fond of having him as a personal bird-cage advisor to let him escape to Earth easily, making Tai Yang's life even harder.
But his behavior starts to change; why? Is Li Jun really only keeping him around for relationship advice? Or does the late-night sight-seeing, and attempts to make him immortal mean something? What do the close proximities, hand-holding, and stares mean? 
The fourth thing that becomes clear to Tai Yang is that he has to disappear before he actually falls for that narcissistic Prince who seems to have no intention of catching him.
...Or does he?
Join Tai Yang to find out!

Prince Not-So-Charming of the Alternate Universe

Lan JiRen and the other guards were quite tired. Li Jun had been waiting outside the doors of the Library for a long time after Tai Yang and Xiao Xia had gone in. Seeing how pale he was, Lan JiRen suggested that he watched over the duo instead.

That was several hours ago, and it was nearly midnight.

One guard yawned. "Hey, don't yawn! You'll make the rest of us-"Another guard started but ended with a massive yawn himself."

Soon everyone was yawning. Lan JiRen bit his tongue to prevent himself from doing the same.

'I have to watch over then very carefully. I can't be falling asleep like this. His majesty didn't look well at all, and he's only allowing me to do this because he trusts me as the 4th strongest Offense type in Changying, so I can't be yawning! Ugh! Get it together!' Lan JiRen thought. He'd been up patrolling the last few nights, so he was exhausted. Nevertheless, being as strong-willed as he was, he kept going.

Doppelgangers.
