She's an SSS-Rank Sentinel, Kept in Captivity by Mad Dogs

[Interstellar sentinel-guide + original worldbuilding + mildly adored by everyone + romantic rivalry + heroine focused on her career + all the mad dogs have one-sided crushes on her] Bound to the last fragment of a god’s will, she is born with SSS-rank sentinel mental strength and appointed crown prince of the Hanhai Empire. Helian Yue, disguised as a man, once thought she had reached the pinnacle of life! But before thirty years could pass, her fortunes took a turn for the worse… A male consort launches a surprise attack and shatters her entire sentinel mental landscape. She has no choice but to activate her second mental landscape and return to being a low-rank female guide. But this is a dark interstellar age, where every guide is born a slave, regardless of status. To reclaim everything, the empire’s exalted crown prince has to become a dark, manipulative sweetheart, spinning and leaping among the hostile Federation forces. “Big brothers, whoever helps my master, the crown prince of the empire, get revenge will receive my mental guidance.” “Big brothers, whoever gets me back to His Highness the crown prince can have everything I have.” “Big brothers, whoever…” To reclaim her rightful place, Helian Yue throws away all dignity. But she never expected these mad dogs to agree to everything in public, then turn around and hunt down her other identity everywhere, even joining forces to destroy the empire. Helian Yue is on the verge of tears. She only wanted to focus on her career. Did they really have to take things this far? Well, then, she can’t be blamed. When mad dogs don’t behave, their master has to crack the whip!
