Silent Longing

DramaWave released it as 78 bite-size episodes, made to watch on a phone in one sitting or a few.

Expect fast pacing and a twist at the end of nearly every episode.

At roughly 2–3 hours in total, it's quicker to finish than most full-length series.

Press play on episode 1 and DramaNext moves on to the next one by itself. No account and nothing to install.
