The Vishnu original story is centered around his role as a supreme being in Hinduism. Vishnu is considered to be eternal and omnipresent. His stories are often intertwined with the cycle of creation, preservation, and destruction. In the original stories, Vishnu sleeps on the cosmic ocean, and from his navel, a lotus grows, and from that lotus, Brahma, the creator, is born. Vishnu's various avatars play crucial roles in different epochs. They come to fight against the forces of evil and protect the good. For instance, the avatar of Matsya (the fish) saved the first man, Manu, from a great flood, which is an important part of the Vishnu lore.

In addition to the above, in some versions of the Vishnu love story, Hanuman also has a connection. Hanuman's devotion to Rama (an avatar of Vishnu) is a form of love in a way. He helps Rama in his quest for Sita. So, Hanuman can be considered as a character related to the Vishnu love story, albeit in a different capacity compared to the more direct love - interest characters like Sita and Radha.
