Fierce Loyalty Masquerading as Annoyance

Few tropes hit harder than the character who complains endlessly about every favor they do, yet moves mountains the moment the other person is in real danger. They will roll their eyes at having to share an umbrella, grumble about bringing a hot meal, or act exasperated by the other's presence—yet their instincts to shield, defend, and show up never falter for a single second. It is the purest form of love disguised as reluctance, where their actions quietly betray every sharp word they speak.
