[Alpha-Omega + interstellar mecha + two powerful leads growing together + Marriage Before Love]
Sikong Jun is the youngest lieutenant general in the empire, but he has one fatal weakness: his pheromones overload. If he loses control, they could damage his mecha. During a battle, his pheromones went haywire and destroyed the nervous system of White Tiger, his mecha. Both White Tiger and Sikong Jun were forced off the front lines and sent back to White Horse Star to recuperate.
On the doctor's advice, the marshal arranged a marriage for Sikong Jun. As it happened, his bride was the Third Prince, who was posing as a painter under a secret identity.
The Third Prince had been well protected by his family since childhood, but he harbored a great ambition, one that had nothing to do with the life he was living. He had long been waiting for an opportunity to fulfill it. When he saw Sikong Jun, he knew this was someone who could help him achieve his ambition. So he pretended to be love-struck, swore he would marry no one else, and begged his father to arrange the match. But the other man shot him down with, "A powerful general is far more useful than a prince consort." Still, there might be a chance.

The elder brother secretly hid the child, using them as leverage to keep the pirates from launching a full-scale attack on the empire.
[Background 2] Rumor has it that a passage to another planet lies beneath the sea of the Central Imperial Star. Merfolk, half human and half fish, live on that planet. It is said that the current Crown Prince was rescued by a mermaid when he was young…
