The male angel favored only the female angel who had fallen into darkness.

Her wings had been scorched by fire; darkness was not a sin, but a mark left from shielding others from curses.

His heart had long since crossed the line of light.

But another female angel, pure and serene, was also grievously wounded in battle.

The love of his brethren forbade him to choose; he could not save only one.

So he broke the first taboo—

He reached out his hands before his heart could stir.

On their three-day journey together, contradictions swirled in the air like whispered prayers:

The black angel knew of his favoritism but dared not respond;

The white angel perceived everything but chose silence;

And he, torn in two between light and desire.

At the gates of heaven, judgment was silent.

Love was seen as a crack that shook order.

He chose repentance.

Not with blood, not with tears,

but with surrender.

He gave up his name,

sealed his heart,

willingly relinquishing his future to any angel. He ultimately wouldn't be with any of them, not because he didn't love them, but because he feared more than love—that they would fall because of him.

Therefore—

He was the Oath Keeper.

He was an angel burdened with love yet possessing it,

He was one who saw darkness yet chose to stand at the boundary between light and shadow.

He did only one thing in his life:

He sent them back to heaven,

While he himself remained forever outside the door.

The male angel didn't want to break the vow, so he didn't choose either of the two female angels. Complete the lyrics.

Okay, I'll help you complete the core theme of "he didn't choose either of them," creating singable lyrics with a focus on the sacred, sorrowful, and forbidden.

"The Angel at the Gate"

Verse 1: He was born standing in the center of light, his wings pure white, unaware of deviation. Yet, on the night he fell amidst the flames of war, he saw for whom darkness grieved.

Her wings were blackened by sin, not from falling, but from bearing the burden for others. The other, quietly fallen in the light, also shed blood and sweat for the Kingdom of Heaven.

Verse 2: The love of his brethren forbade him to turn away, but a stirring of the heart was the deepest sin. Three shadows walked side by side in the clouds, each step treading on the border of judgment.

He knew that once he reached out to embrace, Heaven would be shattered. So he could only fold his love into prayer, hiding it in silence to wait.

Chorus: He chose neither, not because he didn't love, but because he dared not sin. If love would cause them to fall, he would rather be unworthy for life.

He gave his heart to the commandments to be burned, leaving his name outside the gates of Heaven. Both of them were sent back to the light by him. And he... Turning towards the deserted black and white

Verse 3: The black angel understands his favoritism, but only bows his head, remaining silent about the future. The white angel sees through everything, yet still clasps her hands in prayer for his safety.

They live, flying to heaven, carrying his wounds and blessings. He stands at the door, smiling, as if he has lost nothing, yet he has nothing at all.

Chorus (repeated): He chose neither, not out of indifference, but out of ultimate compassion. If love becomes a taboo, he chooses solitude as atonement.

He entrusts his heart to eternal repentance, letting time answer his questions. Two names are called in heaven, but he is left only with silence as his title.

Scene: If one day God asks him if he regrets it, he will kneel, but without shedding a tear.

"I once wanted to embrace darkness and light, but I cannot become their original sin."

Epilogue: Thus, the legend loses a lover, gains a gatekeeper's shadow. He does not belong to any angel—

He is the male angel who gave up love to avoid breaking the precepts.
