I think this is Olaran and Ariala... can't be sure anymore. But I'm sure it was done for AnimeAnimal's Heroes of Hyrule: [link] which is the second story. The first one is called The Hyrule Tournament: [link]

Fic Clip:

"Link, calm down." Aidyn said, entering the tent in an attempt to calm the arguing pair. "If you don't, then I'm afraid that you may have to be punished for showing undue respect..."

"Undue respect to a father that abandoned me!" Link yelled.

The silence that followed seemed to last an age. Link's gaze remained furious and concentrated on his father, while Aidyn's eyes were wide in shock, and he stared at his father in disbelief.

"What is he talking about?"

Olaran stood calmly before them, partially relieved to have the long hidden secret out at last.

"Link, I never abandoned you..."

"I don't believe this." Aidyn said shakily. "You knew, and you never told me? Either of you?"

Link kept glaring at his father, so Aidyn turned to the man himself for answers.

"He's your son? So what, you had an affair with someone before my mother died?"

Link laughed, and it was a laugh without mirth.

"Before our mother died, Aidyn, he betrayed her with the wife of his best friend."

"That's not true!" Olaran snapped. "Aidyn, I never betrayed your mother..."

He put his hand on his son's shoulder, but Aidyn shrugged it off.

"When were you going to tell me?" He asked, his voice filled with hurt. "Or was I never meant to know?"

"I don't know Olaran, why didn't you tell him that I was still alive?" Link said. "You've had every opportunity to in the last seven years."

"Seven years!" Aidyn cried. "You've known for seven years that he was still alive?"

"The son I knew once was dead to me the day I found him again." Olaran said. "He wants nothing to do with me."
