Arthas and Jaina were once in love. They grew up together in Lordaeron. Jaina was a powerful mage, and Arthas was a promising paladin. However, Arthas's thirst for power and his fall to the Scourge drove them apart. His actions became dark and cruel, and Jaina could not follow him on that path. Their love was a tragic one, as Arthas was consumed by his inner demons and Jaina was left to grieve for the man he once was.
Their relationship could be developed through shared memories. For example, they could both recall their time as students in Dalaran. Flashbacks of their innocent days together, studying magic and having friendly competitions, could bring them closer. This could lead to a rekindling of their old feelings in the present of the fanfiction.
One key event was their growing up together in Lordaeron. It was where their relationship began. Another was Arthas's decision to pursue power more aggressively, which started to create a rift between them. And of course, his encounter with Frostmourne was a major turning point that ended their love as he turned into a servant of the Scourge.
One plot idea could be a 'what if' scenario where Arthas didn't fully fall to the Scourge. He and Jaina could work together to heal the wounds of Lordaeron. They might face opposition from both the Alliance and the remaining Scourge forces, but their combined magic and leadership could bring about a new era of peace and cooperation between the living and the undead who can be redeemed.
Arthas' love story is intertwined with his fall from grace. He and Jaina had a relationship that held the potential for a great love story. But Arthas' decisions to follow the path of the dark magic and his encounter with the dreadlords changed him. His sense of justice got warped. He could no longer be the person Jaina loved. His love story ended in heartbreak not only for Jaina but also for Arthas himself as he lost all that was good in him, including his ability to love in a pure and positive way.
The main event was his relationship with Jaina. They were in love, but then Arthas made the fateful decision to take up Frostmourne. This led to his corruption and the end of their relationship.
Since I don't know the exact story, I can't say for sure. But generally in love stories, key elements could be the meeting of the two characters, like how Arthas and Jainas first met. Maybe it was a chance encounter or something more fated.
I'm not sure which specific 'Arthas and Jainas love story' you are referring to. There could be many fictional or cultural stories with such names. Without more context, it's difficult to provide details.
Arthas' sad story is mainly about his fall from grace. He was once a noble paladin, but in his eagerness to protect his people from the undead scourge, he became obsessed with power. He took up Frostmourne, a cursed blade, which slowly corrupted his soul. He ended up killing his own father and turning into the Lich King, losing his former self completely in the process.

[Dawn of Lordaeron] Author: Salted Fish Is Not Here. It's a light novel/derivative doujinshi novel with management and transmigration elements.
User recommendation: A rare novel with Arthas as the main character, and the author has his own interpretation of Wow.
It was a story of 2234 taking control of her own fate and becoming the son of life and death.
The story was based on the shadow realm version, so the interpretation was mostly based on this.
The female lead was still Jaina, and Oni, the Black Dragon Princess, was considered to be doing quite well in these versions.
He looked forward to Oni's coronation as the Black Dragon Queen.
I hope you will like this book.
