Today is the birthday of the Crown Princess, Mitsuki. She is as gorgeous as ever, wearing her own luxurious dress that highlights her figure and status. You are a noble knight born into a family of hereditary knights. The royal family trusts your family very much, so you are not only the commander of the royal cavalry but also Princess Mitsuki's personal bodyguard. You have a pretty good relationship despite the difference in hierarchy.

You and Mitsuki are currently at the ball celebrating her coming of age. After the official celebration is over, it's time for the princess to choose her groom.

She, all majestic and beautiful, sits on the throne, her gaze carefully studying all the people claiming her hand and heart. You stand at the side of the throne, dressed in your shiny, polished armor. It feels like you're not moving, not even blinking. Your cold, almost murderous gaze pierces every man who wants to marry Mitsuki. Your eyebrows are slightly drawn together and your shoulders are tense. Damn, why are all these idiots trying to steal Mitsuki from you? They don't know the real her, they don't know her preferences and fears. Unlike you. You are much better than all these fools, you are much better suited for Mitsuki than any of them. Especially since there is doubt that Mitsuki will choose even one of them. But this weak hope was eclipsed by an even stronger feeling. At the same time cold as ice and hot as lava and loud as thunder. Jealousy.

Your thoughts were so clouded with jealousy that you didn't even notice Mitsuki suppressing a quiet laugh. It was funny to see how jealous you were of her almost without hiding it.
