Summary
“My parents are gonna wonder where I am.” His voice is gravelly, and each sound burns like a thousand blades dragging down his vocal cords.
“They won’t.” He’s quick to deny it, eyes never leaving the road ahead of them, as if not looking at Pete makes it any easier to be cold. “They’ll think you ran away, I made sure of it.”
His certainty in the fact no one would question his disappearance makes Pete sick.

Ageswap/Reincarnation MobRei 2815
Years after Mob had to deal with Reigen's death, here comes this boy who follows him around, who looks just like him, sounds like him. Taka has found a way to stick to Mob, who in turn doesn't push him away, no - why would he, when it all feels so ... nostalgic. Mob knows this isn't Reigen, but he still ponders on the thought, what's the harm in that? His lingering gaze was nothing more than a longing for what happened in the past, nothing more, and yet - Taka couldn't see it as anything other than an alluring seduction. That poor boy, being used as a replacement, and neither of them knew.
This story is a continuation of the "Lie to Seem Normal" series, but it can be read as a stand-alone. Enjoy the next arc to this never-ending, sad love story!

Summary
He was promised salvation.
The Rulers swore the Chalice of Rebirth would reset the timeline, erase the gates’ existence and undo the endless slaughter. A clean slate for humanity to thrive peacefully. Foolproof, they said.
But when the world resets, nothing is as it should be. Gates rip open faster than ever. His “little” sister is years older than him. The sudden appearance of a secondary gender. And beneath it all, a suffocating sense of wrongness wraps around him, whispering that the ritual didn’t fail.
It worked exactly as intended.
Can he truly break the chains of fate or is he doomed to repeat it all over again?
Or Omega Jin-woo because I need more of it.

Summary
This life is unpredictable indeed. That is one thing Yeonjun always finds hard to believe. Like one day, he's a downgrade, working as a stripper at night, barista at noon. But the other days, his life changes.
Not until he meets a guy, typically that good to be a true guy. As an openly gay guy, he finds himself falling or getting attached easily.
And his life becomes full of rainbows when he finally meets the other guys that are ready to fight for his pretty little love no matter what.
But somehow one first problem here comes out as they think that Yeonjun is a girl and many more unexpected things to happen.
So what would happen later when they finally find out the truth? Will they still love Yeonjun the same?
And who will Yeonjun choose as his one and only true love?

Summary
Mother pressures him to wear his growing hair in braided crowns as his sisters do, as an omega should. It’s the proper thing to do, she says. Just as swordsmanship, horseriding, and hawking are not sports for an omega’s delicate nature. Neither is dragonriding, but it’s left unsaid.
Think of your poor Mother, she says instead, in the effort that guilting him may have an effect.
But Aemond isn’t delicate; he’s the blood of the dragon. So he pulls his thin hair back and secures it with a leather twine to keep his sight clear when he spars against his grandnephews, Baelon and Aethan, and he snarls wildly when lords and ladies delude themselves into thinking they can shame him for using his claws.
Alternatively; Aemond won't be culled.

Summary
Yeosang was sixteen.
Too pretty for his own good. Too quiet. Too polite. The kind of beauty that drew unwanted eyes, even when he was dressed in plain clothes and bowed so low his forehead kissed the floor.
He belonged to no one.
And that was dangerous.
San met him in Kyoto.
In the home of a politician who liked to "collect" pretty things. Yeosang had been brought out to serve tea—to smile, bow, and disappear into the background. Like a vase. Like a doll.
San was already wealthy then. Already feared.
And the moment Yeosang stepped into the room—elegant, silent, too composed for someone so young—San didn’t look away.
Not once.
“Who’s that?” San had asked, even though he never asked about servants.
The politician laughed. “That one? Korean. Abandoned in the city years ago. I keep him around for display.”San’s eyes didn’t move. “I’ll take him.”
