I, The Substitute, Am With The Main Character

He Xulan is a heartthrob, adored by everyone. The new emperor likes him, the prime minister and generals in the court admire him, and the late emperor even had the Astronomical Bureau fabricate the absurd lie that marrying He Xulan would cure his illness, just to make him the lord empress.
As for Xueya, he is merely a substitute used by those who can’t have He Xulan to amuse themselves.
At first, Xueya only wanted to survive, even if it meant wearing clothes meant for women. But then he discovered that his dreams could predict the future. In that future, he meets a tragic end, dying in the palace with his body wrapped in a straw mat. Wanting both life and wealth, Xueya decisively decides to replace He Xulan. Thus, he embarks on various paths of sabotaging He Xulan in various ways, even going so far as to sow discord between He Xulan and others.

But one day, when he sneaks out of the new emperor’s palace late at night wearing a skirt, he encounters a drunk He Xulan.
The next day, Xueya sees the skirt shredded into strips…
From that day on, his skirts always end up shredded in He Xulan’s palace, and he no longer needs to fake the marks on his body…
[Reading Guide]
He Xulan is the top, a heteros*xual man in the face of men other than the shou; facing the shou, he automatically bends like mosquito coils.
The top only likes the bottom, with an exceptionally thick arrow, which is not evident in the early stage and has no intimate behavior with others.
The bottom is a pretty fool.
