Xie Yu and Qin Lie have been raised as their families' heirs since childhood. Their names have been repeated in each other's ears since they were infants.
Xie Yu is always hearing his family talk about how outstanding Qin Lie is and tell him to learn from him.
Qin Lie is always hearing his family talk about how outstanding Xie Yu is and tell him to measure up to Xie Yu.
The two prodigies have always lived in each other's shadows.
As a result, they are constantly competing in secret. If one enters a competition, the other has to enter it too.
They even compete to see who can be the elementary school's most sunny, cheerful student.
They remain evenly matched until college.
After they start college, Xie Yu loses.
On the first day of school, Qin Lie awakens as an S-rank Sentinel and joins the elite class for special training.
Meanwhile, Xie Yu is still attending evening study sessions and working on group projects in the regular class.
After that, no one dares risk bringing up Qin Lie in front of Xie Yu.
When nearly all the students have differentiated, Xie Yu finally differentiates before the start of his second year.
An angelic spirit form, an S-rank Guide.
On a planet where there are a hundred times fewer Guides than Sentinels, an S-rank Guide is a national treasure.
Before the new school year begins, Xie Yu receives an order on his terminal to soothe a Sentinel suffering a mental breakdown.
When he walks into the assignment room, he finds his archenemy, Qin Lie, tied tightly to a chair in the huge room, wearing an inscrutable smile.
"Well, hello there, my personal Guide."
The main planet's top military academy begins the new school year.
Two people step out side by side from a luxurious mecha-car.
The students turn their heads and exclaim, "Whoa! Isn't that Xie Yu and Qin Lie? They can actually stay together peacefully within one meter of each other for more than three seconds!"
A month later, a picture blows up the campus forum and crashes the university network.
In the picture, a Guide's exclusive mark encircles Qin Lie's neck. A red glow extends from the mark, its other end wrapped around Xie Yu's pale wrist.
Under an exclusive bond, if the Guide dies, the Sentinel can never again accept soothing from another Guide and will eventually die from a mental breakdown.
Everyone speculates that Xie Yu is planning to take Qin Lie down with him, choosing to die rather than let Qin Lie get the better of him.
Meanwhile, in the soothing room, Xie Yu is drenched in sweat, his mental energy depleted.
Qin Lie has evolved again and again!
Tied up from head to toe, Qin Lie tilts his head back, pain showing between his brows, while a defiant smile plays on his lips.
"Your body fluids and scent calm me better than mental energy, my personal Guide. Xie Yu, come over and give me a kiss."
