Summary: Tsuna and Reborn were lovers before Tsuna was banished to the human world as a normal school boy, losing all of his memories. Reborn—still a member of the heaven—risked his position to fly down and visit the boy, protecting him. The day when Tsuna's memories regain was the day of Reborn's death. Angel and half-angels, they can't be together. There's always a border between them.

A/N: …Random idea when I was day dreaming and staring at peoples who were walking on the streets. I was wondering if any of those humans were angels who were banished to Earth. Ha-ha, I know it's weird. ==" Anyway, enjoy!

Warning: My first time writing this kind of story so please bear with the weird names or places or situations I wrote.

Prologue: The Incomplete Angel

The brunet giggles when his boyfriend kissed him on the neck. They were in the Heaven's kingdom, in their mansion. Each angel was provided with a mansion to live in. Tsuna and Reborn shared a mansion like husband and wife. Nobody questioned it as long as they did not show their affections in public.

Reborn was just going to tear off Tsuna's clothes when the door opens. Two guards and the assistant of their King walk in. Reborn sat up immediately, followed by Tsuna. Both of them stare with confusion. The assistant, Demonia, pulls out a scroll and opens it.

"As the assistant and most trusted man of our King, I have brought the message of his Highness," he started. Reborn and Tsuna immediately kneel down on the ground. It was a courtesy whenever the message of the King was about to be announced. "After a few inspections and researches, his Highness had found out that Tsunayoshi Saint does not deserve to live among us, the angels."

Tsuna's eyes widen. "What do you mean?" his voice shook.

Demonia's face was blank. "It was revealed that Tsunayoshi Saint belongs to the human realm as the researches prove that he is half-angel and half-human. Therefore, his Highness had made a decision to banish Tsunayoshi Saint to the human world rather than letting him stay in Heaven because he might attract the human-thirst demons." He finishes.

Reborn turns and stares at Tsuna in disbelief. "Tsuna…?" he starts slowly. Tsuna bites his lips. How did they found out about his identity? "You are…a half-angel?" the black haired man asks slowly, whispering.

"I…"

"His execution from the Heaven will begin tomorrow before the Sun appears." Demonia says before disappearing into thin air with his guards. Probably back to the palace, obviously. After the three of the royals left, Reborn and Tsuna sat on the bed.

"Tsuna…why didn't you tell me about this…and how did you manage to live in here for so long?" Reborn's voice trails away. Tsuna notices that his eyes had started to turn stranger and distant and he did not like it, not even one bit. He looks back at Reborn with teary eyes.

"I'm not, Reborn! I'm a whole angel; it was all proven in the Confirmation Ceremony. You were there too!" The brunet says, still trying to protect his identity. He did not want to be banished to Earth! He wanted to stay with Reborn forever.

Reborn shakes his head. "I don't know, Tsuna. Yes, it was proven but who knows if you have done some tricks in it? Who knows if you were using strings during the voyage test, you stole the energy balls from other confirmed angels during the power test and you wrote answers on your palm during the trivia?" he asks slowly, doubt creeping in his voice. Tsuna felt his heart being smashed.

How Reborn could think of him as a liar?

"If you don't believe me, no one else will. Do you believe me, Reborn?" he asks hoping that his boyfriend would say yes.

Reborn did not say anything. He did not know what to say. Tsuna bites his lips and tears starts to course down. He turns away and walks out of the room disappointed, closing the door behind him.

Tsuna walks down the stairs, heading towards the dining room. He opens the cabinet and found a bowl of candies. He takes it out and sits on the counter, munching on the candies. He was still thinking about his execution tomorrow. How did the King even know about this? His identity was protected for thousands of years; he was not found out even once and he did not do anything that could make people doubt his identity. So how did they know?

He had known that he was half angel when he found the album in his late father's room. His father was killed during the Demon and Angel War thousands of years ago. Then his mother disappeared mysteriously. The album contains of photos when his parents date, before he was born. In the album, there was one photo that made him clear of his identity.

A photo of his father and his mother along with his mother's mortal family was slipped behind the album.

So his mother was a human, how did she marry his father then? Marriage between the angels and mortals were forbidden and the mortals who committed this crime will be banished to the human world and the memories of them being in Heaven will be erased permanently, whereas for the angels they will be locked and died from depression.

Maybe mother had gone to the Human world. Does that mean she does not remember anything? But why did she left? Why didn't she take me together? And how did she come to Heaven without being busted?

Thousands of questions swirl in his mind. He wants to know the truth. He wants to know why his mother didn't take him. Why he was left on Reborn's doorstep when he was ten. So many questions left unanswered. What was his mother hiding from him?

Finally, Tsuna got tired and fell asleep on the table of the counter. When he opens his eyes, he was already in the Execution Court, in the Cloud Prison, ready to be executed and banished to Earth for being a half angel.

A/N: I have already prepared the next chapter :P So if you want, review? Tell me how you think of this prologue. Did it suck? Was it interesting? I might update tomorrow or…Saturday. School starts on Wednesday. By the way, I wrote this chapter listening to Bang Yongguk feat Daehyun – I remember. It's really a sad song if you read the lyrics.
