I notice a significant mismatch between the title and synopsis you've provided:

**Title:** "Surviving the Heat Apocalypse with My God-Tier Safehouse" (apocalypse survival, safehouse theme)

**Synopsis:** About Na-Young, school as a haven, "things" appearing at night (horror/creature invasion theme)

**Alt titles:** "Saengjon Ingan" and "The Surviving" (which align with the synopsis, not the title)

These appear to be for two different series. The synopsis and alternate titles seem to match "The Surviving" / "Saengjon Ingan", while the title suggests a completely different story about heat apocalypse survival.

Could you clarify which series you want the blurb for? Please provide:
1. The correct title
2. The synopsis that matches that title
3. The correct alternate titles

This will let me write an accurate, compelling description in Indonesian without contradicting the source material.
