I am a shameless Whouffaldi shipper. The series is three short-ish one-shots.
On ff.net:Thorns The Doctor has a major meltdown in front of Clara, and the reason for it is more complex than it seems.
Pocket Chalk The Doctor is a mess after he gives his last box of chalk to Clara. He finds comfort in the smell of chalk, and not having any around is very upsetting.
Shatter the Rules The Doctor and Clara stop running from themselves because rules were made to be broken. (NSFW)
Whouffaldi Triad A short trilogy where the Doctor and Clara stop running away from their feelings.
Gosh darn it, I just want Twelve and Clara to have some happiness!
