Return

This is “Return 2,” a short horror webcomic by Korean artist K.S (also known as K.S. Park), part of a series of very short, creepy 4-koma/8-koma style stories. It’s a classic example of the “we adopted a ghost/demon child without realizing it” trope, told with escalating dread.
Here’s the full sequence and what actually happens (spoilers, obviously):

Title screen: “Return 2” – a dark house under a full moon. Already sets the mood.
2.–6. A nervous couple (sweating the whole time) are watching horror movies, jumping at ghosts on TV, getting paranoid at every noise, etc. They clearly live in constant fear.
They finally seem relieved and affectionate with each other… until the wife looks terrified again.
8.–9. The husband is aggressively dragging their “daughter” (short blonde hair, black dress) by the arm while the wife cries. The child looks blank/scared.
10.–11. The wife hugs the child tightly while the husband stands in the background looking defeated/sad.
The child is literally being sucked out the bedroom window by a huge ghostly hand/arm made of black smoke. Text at the bottom: “Stay. We need you more than you think.”
The husband carries the child back inside on his shoulders; the wife looks relieved but still sweating.
14.–15. Later, the family is together again, but now the parents are looking out the window in terror at another ghostly figure staring in, while the “daughter” cries.
Final panel: The parents are hugging each other in front of a mirror. In the reflection, the “daughter” is standing behind them… smiling creepily with completely black eyes.

The twist/reveal:
The little girl is actually a malevolent entity (demon/ghost/yōkai-like creature). The real daughter died (or was taken) earlier, and this thing replaced her. The ghostly arm in panel 12 wasn’t trying to abduct the child — it was the spirit of their real daughter (or some force of good) trying to pull the impostor monster out of the house to get rid of it.
The parents, out of desperate grief and attachment, fought to keep the monster and dragged it back inside, essentially choosing to live with (and be slowly tormented or possessed by) the evil entity because they “needed” their “daughter” so badly, even if it wasn’t really her anymore.
That’s why the comic is titled “Return 2” — this is the second time the real daughter tried to return (or the second time the monster has successfully come back into the house).
It’s a brutally dark little story about grief overriding survival instinct, told in just a few panels. Very effective Korean-style horror.1.9sFast
