The synopsis is extremely brief: "A teenaged hired killer stays at Hotel Inhumans while infiltrating a high school for a job."
The sources provide context about the series (it's an animation, it's based on a manga, it's about a hotel for assassins, the concierges are Ikurou Hoshi and Sara Haizaki).
Problem: The user wants a 280-380 word recap for a specific episode (S2E1). However, the provided synopsis only covers the plot of that episode (presumably), and it is only one sentence long.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." "Never invent or guess... plot points."
If I write 280-380 words based on a one-sentence synopsis without inventing anything, I will fail the word count requirement.
Wait, the prompt says: "Write a grounded 280-380 word episode recap... If the synopsis is sparse, stay concise rather than guessing."
This is a contradiction. If I stay concise (as instructed for sparse synopses), I cannot hit 280-380 words. If I hit 280-
