The Pitiful One Isn't Everyone's Scapegoat [Quick Transmigration]

Blurb:

As the lowest-ranked tasker in the Transmigration Bureau, Ye Ke must travel to different worlds to complete the tasks assigned by the bureau.

Ye Ke is an unfeeling tool who leaves without hesitation once a task is done. He never expects to become a wound that so many people are unwilling to touch.

World One: "A disabled omega doesn't deserve to set foot in the Nie family's home."

Once a beloved who was sacrificed as a cannon-fodder character for the child of destiny, Ye Ke no longer spends ten years waiting for someone who will never return. He lets go of his obsession and makes peace with his regrets. After he leaves, the tears the man sheds at his grave are the farewell Ye Ke waited ten years for but never received.

World Two: "I'm fluffy, and nobody can resist how handsome I am."

As the cutest hamster in the entire universe, Ye Ke is troubled by how to find a pet owner for his second-cutest little friend in the universe. When Ye Ke runs headfirst into the arms of the child of destiny, he trembles and grabs hold of his friend, whose eyes are shining.

Not him! Anyone with the aura of destiny is a walking bad-luck charm!

World Three: "This ill-omened black dragon brings nothing but misfortune."

Ye Ke brings back a pitiful little one he found in the abyss. The poor thing grew up without parents, hated and exiled by his own people. Thanks to Ye Ke's care, a light finally appears in his eyes. He loves clinging to Ye Ke, like a sticky little sugar cake.

Ye Ke fails his mission for him, while the little sugar cake defies heaven for Ye Ke, eventually becoming the villain destined to be destroyed by the protagonist.

[Guide]

In World One, the original host is the one who has a romantic connection. The protagonist is just an unfeeling single dog!

Premise: The world has light because you bring warmth.
