Selfless, abstinent top x dark-hearted, gloomy bottom
Fernando x Ryan
Ryan was descended from Italian nobility in the twentieth century. When he was six, his father was framed by villains, and the family was ruined overnight.
He was adopted and raised by Mr. Fernando, a friend of his late father.
When Ryan was sixteen, Mr. Fernando baptized him and became his godfather.
Mr. Fernando was a generous, gentle gentleman. Unfortunately, his guidance did not make Ryan gentle.
Ryan uncovered the truth behind the plot that had ruined his family, and was determined to make those responsible pay in blood.
Then an accident happened.
He was in a car crash. When he woke up, one small thing about his life had changed.
He had lost some of his memories.
Besides that, one day he discovered that there were far too many love letters hidden in his room.
Their wording was unbearably sappy.
But the handwriting... Ryan thought it looked familiar. Looking closer, he realized it was Mr. Fernando's!
Mr. Fernando had been secretly in love with him all along!
It was a shocking, forbidden scandal!
Mr. Fernando was a good man, and exceptionally handsome, too.
Mr. Fernando also had a pair of blue-gray eyes.
He always said gently and warmly, "Come, child. Come here to me."
But... no matter what, Ryan saw Mr. Fernando as a father.
How could a father love his son that way?
Ryan didn't want people to look down on Mr. Fernando.
He quietly moved out, hoping to nip this twisted love, which could destroy them both, in the bud.
He went to a neighboring city, thinking he'd escaped Mr. Fernando's sphere of influence.
But at a ball, a luxury car blocked his way.
The car door opened, and an expensive, elegant cane touched the ground.
Then the guests at the ball saw a handsome gentleman in a suit step out of the car.
Ignoring everyone's stares, the gentleman walked over to the obscure young man in the corner and said, "Ryan, it's late. You should go home and rest."

Mr. Fernando had a godson.
Handsome and clever, he had taught him from the age of five: how to read, how to write, until even his handwriting became identical to his own.
But before long, he realized his godson had improper feelings for him.
Just as Mr. Fernando was wondering how to handle it, Ryan was in a car crash and lost some of his memories.
Losing those memories should have been a good thing.
But Ryan went too far.
He moved out, sought refuge with the Sith family, and treated him like a stranger.
That was... something he couldn't tolerate.

"Father, are you afraid to look at me, too?" Ryan asked.
Fernando looked at the young man's pale, lean body and closed his eyes.
He silently prayed.
"My Almighty Lord, forgive my desire."

One-on-one, both leads have no prior partners.
Older top; the exact age gap is undecided, but definitely no less than ten years. That's just what I like.
