Since I cannot access or play the file directly, here is a based on what the filename and common MKV standards reveal:

: If the original file was too large for certain hosting services, it may have been divided into "pieces." You usually need all pieces and a file joiner (or a player like VLC) to view the full episode.

: For Jian Qing, the "princess in trouble," this deal represents a lifeline to resolve her family's debts and navigate her new reality.

It might be tempting to click a direct link to that S01E02 file. However, downloading pirated .mkv files from unverified sites like KatDrama poses serious risks.

Without mediainfo output, I cannot confirm:

Websites like KatDrama.com (now operating under various mirrors) have historically catered to this demand by ripping official streams, dubbing them unofficially, and packaging them into .mkv containers.
