The Interstellar Mercenary Code [GB]

Blade, an elite interstellar mercenary group. Yueling, a rookie who is just starting to make a name for herself at Blade. A selection held by the Tower assigns Yueling a special mission. “Listen up. This is a protection mission! Don't go chopping the target up in the middle of the night!” “Boss, do I really seem that violent to you?!” Yueling happily starts packing. “And countless people are watching this selection. Remember your identity. During the selection, you're Wick, the second son of the Council Speaker's girlfriend. You're a Guide, a delicate, frail Guide!” “Got it, got it! I'm great at pretending!” “And the rules in the yellow book, ” “Understood, understood.” “You, ” “I'm off, boss!” And so Blade's boss watched her leave, deeply worried. As it turned out, she was right to worry. One night, the boss received a call from Yueling. Her voice was troubled and conflicted. “Boss, the yellow book doesn't say what to do if I sleep with the target.” The boss's voice shot up. “You slept with the Council Speaker's son?” “Uh, no.” “Then it's fine. It's just sleeping with someone. Who did you sleep with?” “Um... Lucien.” “Lucien... who?! Are you saying you slept with the Federation President's son?” Lucien Nord is the only son of the Federation President, an S-rank Sentinel. He is disciplined, cautious, steady in everything he does, and exceptionally capable. If all goes as expected, he will inherit the presidency and become the Federation's next leader. But the unexpected happened during this selection held by the Tower. Lucien watches the Guide called Yueling fight side by side with Wick, his gaze shadowed, a trace of murderous intent impossible to suppress. Yueling has already helped him with his mental stabilization, so she is his Guide. If she still refuses to break up with Wick, he doesn't mind dealing with Wick himself. After all, he's wanted him dead for a long time. Reading notes and content warnings: 1. This is a gender-bender romance, Sentinel/Guide, both leads are each other's first and only. 2. The couple are rivals who keep butting heads. Please don't read if that's not your thing. 3. Interstellar Sentinel/Guide setting with lots of author-created worldbuilding. Theme: I love you, unwavering until death
