While Princess Turandot may act high-and-mighty, deep down she just wants to be loved. Although adored by all in the palace, she rarely has a chance to encounter an eligible bachelor. While she gives others the impression that she isn't interested in marriage, even going as far as to require anyone who wants her hand to pass three difficult trials, she secretly pines for the right man who she hopes will soon appear in her life. Contradictory? Yes, but aren't all young girls like that? No Name, a good-looking dandy from a downfallen family who is skilled at both letters and martial arts, and who lives a recluse life on an island, sees a portrait of Princess Turandot and falls in love with her at first sight. Unable to forget her intoxicating looks, he is determined to head to the palace to seek out the beauty. Even Liu Er, a girl who admires him, can't stop him. Liu Er follows the footsteps of No Name to the palace city. However, her love remains unrequited, and beyond those city walls is an abyss impossible for her to cross. In the end, Liu Er decides to take her life, instead of giving in to her fate. The gushing crimson blood is the last and only witness to her conviction of keeping her ""promise"" for No Name. Turandot, feeling remorseful upon learning of Liu Er's death, wishes to atone by going with No Name, and loving him as deeply as Liu Er did. Yet, No Name, broken-hearted by Liu Er's death, makes his way home alone, unwilling to take Turandot as his mate. Liu Er, who sacrifices herself for love, dies an epic but sad death, tear-jerking and also inspiring.
