The Elusive Vermilion Rose (смешанная)

As the revolution builds in Larussia, a masked vigilante appears to whisk those destined for execution to safety. Not about to have his plans ruined, the king gives his two sons an offer they can’t refuse: discover this masked man’s identity if you wish to be heir to the throne.
The youngest prince knows this is his only chance at the throne, while the older prince, Victor, finds himself caught in the middle; as his curiosity about the elusive Eros dances ever closer to affection.
Meanwhile Yuuri Katsuki, a tailor from the neighboring country of Yamato, has been traveling back and forth more than usual... clearly because of the nobility clamoring to have the emperor’s own tailor make their clothes. And Yuuri and his three friends definitely don’t have anything to do with the so-called masked vigilantes in the Society of the Vermilion Rose. Nope, not at all.
