The Paper Demon King

Chi Yu had always kept a secret: he was a very rare kind of guy, a BL fan who was only into shipping men, not men himself. Before he transmigrated into a book, he could only secretly ship same-sex couples. But after he transmigrated and got bound to a self-proclaimed King of Shipping System, he completely let himself go.

Even when he passed two dogs on the street, he had to ship them!

[The literature committee member and her childhood friend grew up together, and the committee member even chose this school just to be with her. A childhood friend who showed up out of nowhere, isn't that just perfect? She even reaches out to straighten her friend's stray bangs...]

[The lilies of my hometown are blooming.]

The childhood friend: ...

[The top student class monitor and the science genius: one is warm as the sun, the other is aloof and chaste. And that ridiculous height difference! They're a match made in heaven! They came in together, and even their strides match...]

[The chrysanthemums of my hometown are blooming too.]

The two top students: ...

[Whoa, a beautiful art student with shoulder-length hair, looking so delicate and easy to bully, just transferred to the back row. They say nine out of ten art students are gay, and the last one is still deciding. I wonder if Yan Xi is the bottom, or the one who's still deciding?]

Yan Xi: ...

The next month, the art student pinned him against a tree and said, "Little BL fan, wanna ship me with you?"

[Ah, the roses of my hometown... Wait, no, my rose is here.]
