This is the complete set of 16 episodes ranging from 66 to 91 minutes long each. They all have edited "soft" English captions; that is, English subtitles are part of the MKV file and the subtitles can be enabled or disabled as you wish.

I downloaded the source videos named like "Love.Next.Door.S01E01.1080p.NF.WEB-DL.x264.DDP2.0-ADWeb [DRAMADAY.me].mkv" and extracted the English subtitles from those. Then I...
- Used Subtitle Edit (by Nikolaj Lynge Olsson) to find and fix all flagged issues
- Added 0.7 second to each subtitle (where possible) to allow more time to read them and adjusted words/minute to at least 280
- "Softened" all subtitled profanity (bastard --> jerk, damn --> darn, bitch --> witch etc.)
- Used Handbrake to create new MKV files using my subtitles, trimming off the obscenely-irritating Netflix logo from the starts and endings
