Why did Draupadi have 5 husbands in the Mahabharata?

I see many people answering that it's because of Kunti’s command, but it's actually completely wrong.

When Arjuna won Draupadi and brought her home in the Potter’s street, Kunthi was in the kitchen when the brothers arrived. Bhima, wanting to sound lighthearted, cried from the door- step, "Mother, come out, see what Arjuna w has brought today." Without coming out, Kunthi answered from the kitchen, "Very well, share it among yourselves." ."Oh!" exclaimed Bhima. "Oh! Oh!" cried everyone, and the loudest exclamation was from Arjuna, who had won the bride.The mother came out to see why there was such an uproar and cried, "Oh! Who is this you have won, Arjuna?" She was full of joy, and clasped the girl's hand. "Oh! Arjuna, you have won this-bride, this Princess, this lovely creature!.”.Kunthi tried to make light of her own advice and said with a simper, "Of course, I did not know what you meant when you said you had brought Arjuna. I thought it was the usual gift of alms ." Her voice trailed away.It was Arjuna who broke the awkward moment. "Mother, your word has always been a command to us, and its authority is inescapable. How can it be otherwise? We will share Draupadi as you have commanded.". "No, no, no..." cried the mother.

So, Kunti never wanted Draupadi to be be shared by 5 husbands. At that moment, Vyasa(their Grand father ) came and told that Draupadi is destined to be the wife of 5 husbands. Vyasa narrated the story:-

Draupadi was called Nalayani in her last birth. She was one of the five ideal women in our land. She was married to a sage called Moudgalya. She displayed the utmost devotion to him as a wife. She obeyed all his erratic commands, accepted his fickle moods, submitted herself to all his tyrannical orders, and ate the scraps from his plate. All this she did without hesitation or mental protest, totally effacing her own ego. They spent many years thus, and one day her husband said, 'O'beautiful one, perfect wife on earth, you have indeed passed through the severest trial and come through unscathed. Know you that I am neither old nor diseased nor inconsiderate. I assumed this vicious and disgusting appearance in order to test you. You are indeed the most forbearing partner a man could hope for. Ask me for any boon you may fancy, and I will grant it.' "Nalayani said, 'I want you to love me as five men, assuming five forms, and always coming back to and merging in one form.' And he granted her the wish. He shed his unpleasant appearance in a moment and stood before her as an attractive, virile man and he could assume four other forms too. The rest of their life was all romance; they travelled far and wide, visited beautiful romantic spots on earth, and led a life of perfect union, not in one, but several worlds. They lived and loved endlessly. She never got tired of it, but he did. He told her one day that his life of abandon was at an end and that he was retiring into loneliness and introspection. At this she wailed, 'I am still insatiate. I have lived a wonderful life with you. I want you to continue it for ever. Moudgalya rejected her plea, warded her off as a drag on his spiritual progress, and departed. Whereupon she came down to earth from the dreamy elysium in which she had dwelt and prepared herself to meditate on Ishwara the Almighty. She meditated with great rigour, and when Ishwara appeared before her, she muttered, 'I want my husband, husband, husband. You will soon end this identity and will be reborn as a beauty and marry five husbands,' said the god. "Five husbands! God! Why five? I want only one.'."I cannot help it. I heard you say "husband," and that five times,' said Ishwara. And that proved the last word on the subject, since a god's word is unretractable. "While it seemed as if the god had spoken in jest, he had his purpose. In the vision of a god there is no joking, everything works according to a scheme. Nalayani was reborn as the daughter of Drupada without being conceived in a womb, but out of a sacrificial fire. Justice and goodness have to be reinstated in this world.

This is the real reason behind Draupadi having 5 husbands.
