Major and Minor Spoilers:
Marius and Cosette are two young characters in Les Mis. Just like Fiyero and Elphaba, they are part of a love triangle. But the triangle stays the way it is, which would be during the entire show, Eponine would have unrequited love the entire time and than Marius and Cosette would be a couple the entire time. So Les Mis’ love triangle is straight-forward because it keeps the set up.
Marius and Cosette help bring hope to the story. Les Mis after all is quite a tragic musical. Cosette represents hope and light to the story and that is one of the biggest reasons why she had to fall in love with Marius in the first place. Marius and Cosette wouldn’t have become a couple if it wasn’t for Eponine looking for Cosette. Eponine risks her life several times to make sure those two stay together. Marius and Cosette deserve to stay together. Another reason why I love those two together has to do with the switch that happened between Eponine and Cosette. As children, Eponine was spoiled and seemed to be loved and Cosette was treated like a servant and unloved, but when they get older, the situations are the opposite.
Of the characters who not die, Marius and Cosette are my favorite characters. I love Cosette due to the light and hope she brings to the tale. I love Marius because of how awkward he can be, the level of compassion and bravery he can show, and how nice and sweet he is. These two are just perfect for one another. Many people have said that Marius should have been with Eponine, but I disagree on that fact. The love triangle is so fascinating and it works so well because it perfectly blends together light and hope with heartbreak and pain. In addition, when it comes to love triangles, understanding why you love the couple, you sometimes need to bring up the unrequited love situation.
