#which is what in universe sources run with (Daeron's death prior to Tessarions battles against Seasmoke and Vermithor)

[waitingforsecretsouls]

Much as I theoretically understand why fandom glomped onto the possibility of the tragic Daeron and Addam romance, it genuinely doesn't seem like the closest explanation the text itself offers. One of the biggest implications people see for this is the paragraph wondering about Tessarion's motivations for intervening in the Vermithor vs Seasmoke fight:

Vermithor’s size and weight were too much for Seasmoke to contend with, Lord Blackwood told Grand Maester Munkun many years later, and he would surely have torn the silver-grey dragon to pieces…if Tessarion had not fallen from the sky at that very moment to join the fight. Who can know the heart of a dragon? Was it simple bloodlust that drove the Blue Queen to attack? Did the she-dragon come to help one of the combatants? If so, which? Some will claim that the bond between a dragon and dragonrider runs so deep that the beast shares his master’s loves and hates. But who was the ally here, and who the enemy?

People tend to focus a lot on the love aspect and basically ignore the alternate possibility offered up, which is hate as a motivating force.

As happy as I am for people enjoying the concept of Daeron/Addam, let's acknowledge that they have neither actual on page interactions nor as much as implied aquaintanceship, and GRRM is the opposite of subtle when it comes to "hinting" at these things for implied same sex entanglements. One line about Addam, who canonically served on his mothers trading cogs, having previously traveled as far as Oldtown, or Daeron enjoying spending his off - time at Oldtown's or prior to his fostering King's Landings harbour or shipyards would have been sufficient, but instead there's absolutely nothing.

Whereas Daeron and Hugh Hammer, dragonseed and rider of Vermithor, do have canonical interactions, both on page involving dialogue and implied by their close proximity, that develops into a plot relevant enmity, culminating in Hugh stating he'll claim Daeron's birthright for himself, as rider of the largest surviving dragon, and Daeron approving the Caltrops assassination of Hugh in turn.

With his brother Aemond slain as well, the greens found themselves kingless and leaderless. Prince Daeron stood next in the line of succession. Lord Peake declared that the boy should be proclaimed as Prince of Dragonstone at once; others, believing Aegon II dead, wished to crown him king. The Two Betrayers felt the need of a king as well…but Daeron Targaryen was not the king they wanted. “We need a strong man to lead us, not a boy,” declared Hard Hugh Hammer. “The throne should be mine.” When Bold Jon Roxton demanded to know by what right he presumed to name himself a king, Lord Hammer answered, “The same right as the Conqueror. A dragon.” And truly, with Vhagar dead at last, the oldest and largest living dragon in all Westeros was Vermithor, once the mount of the Old King, now that of Hard Hugh the bastard. Vermithor was thrice the size of Prince Daeron’s she-dragon Tessarion. No man who glimpsed them together could fail to see that Vermithor was a far more fearsome beast. [...] The lords and knights of Oldtown and the Reach were offended by the arrogance of the Betrayer’s claim, however, and none more so than Prince Daeron Targaryen himself, who grew so wroth that he threw a cup of wine into Hard Hugh’s face. (...) Lord Hammer said, “Little boys should be more mannerly when men are speaking. I think your father did not beat you often enough. Take care I do not make up for his lack.” The Two Betrayers took their leave together, and began to make plans for Hammer’s coronation. When seen the next day, Hard Hugh was wearing a crown of black iron, to the fury of Prince Daeron and his trueborn lords and knights.

[...] Though Prince Daeron was not present at the council, the Caltrops (as the conspirators became known) were loath to proceed without his consent and blessing. Owen Fossoway, Lord of Cider Hall, was dispatched under cover of darkness to wake the prince and bring him to the cellar, that the plotters might inform him of their plans. Nor did the once-gentle prince hesitate when Lord Unwin Peake presented him with warrants for the execution of Hard Hugh Hammer and Ulf White, but eagerly affixed his seal.

Which seams like a far more (meaning: at all) established backdrop for that musing about sharing loves and hates to me.

Tldr; Less "love wins" and more "haterism transcending death" for Daeron the Daring.
