Forced to fall in love with three alphas in a comic book

Chao Xun transmigrates into a comic set in a world with six genders, and has the misfortune of inhabiting the body of a universally despised side character who had been obsessively chasing the male lead shou. Mi Yu is not only the campus heartthrob but also a school tyrant with a notoriously terrible temper, and he had long since lost all patience with the original host’s relentless pestering. Chao Xun’s plan was simply to lie low and keep as far from the male lead as possible, but a system suddenly appeared and told him: “Want to go home? First win Mi Yu’s heart.” Chao Xun: “…Excuse me?”
Having been single for years, Chao Xun finds himself forced to learn how to court an alpha, determined to win over the male lead shou before the male lead gong ever enters the picture.
Mi Yu: “You love me this much already. I suppose it wouldn’t hurt to like you back a little.”
Then one day the system notifies him of a gender bug. On the morning he comes of age, he publicly differentiates not into a beta as expected, but into an omega. The male lead gong, who happens to be present, catches his pheromones and instantly understands: Chao Xun is his fated mate. After secretly running a pheromone compatibility test behind Chao Xun’s back, the result comes back at 99%.
Yuan Chuan Si: “I have been holding myself back this whole time. I refuse to be the kind of despicable person who uses pheromones to coerce you.”
System: “Second mission now unlocked: save Yuan Chuan Si.”
Chao Xun: “How?”
System: “Date him.”
Chao Xun: “……”
Forced to break up with Mi Yu and turn his attention to the male lead gong, Chao Xun assumes that once this relationship is wrapped up he will finally be allowed to go home. But then the original host’s older brother, who had been living abroad, suddenly returns.
Chao Ling Xue is a man of extraordinary intellect and untouchable elegance, like a flower growing from a mountaintop. He fixes Yuan Chuan Si with an icy stare: “You thought pheromones alone would be enough to take him away?”
What is even more alarming is that Chao Ling Xue can apparently see the system living inside Chao Xun’s head.
System: “For my own safety, you’d better get ready for a third relationship.”
Chao Xun: “!!!”
Chao Ling Xue: “Will you continue to love me the way you once did, completely and without reservation?”
In the end, the system lays all its cards on the table: I arranged all three of them for you. But do you really not love a single one of them?
Chao Xun is equally baffled: Was I not showing enough love?
