I, a good-for-nothing elf who was just waiting to die in the Elf Valley, was suddenly captured and asked to marry on my behalf! Oh no, it was a proxy marriage - my irresponsible brother ran away from the marriage, leaving me, my sister, disguised as a man to be his groom. I thought I would be discovered, but unexpectedly, the legendary cold-faced prince of hell not only did not expose me, but also took care of me in every possible way and gave me snacks every day. I was moved, but I found him hiding in the garden, secretly wearing skirts, fluttering at butterflies... Wait, is he also a woman? Good guy, one is marrying by proxy, the other is marrying by proxy, we two are really energetic in acting as a fake couple! However, since everyone is an actor, shouldn't it be time to negotiate the price of the position of princess?
