I am mixing actual series and their fanworks too.
Sailor Moon: Try watching the ending of Stars without crying!
Harry Potter: So much feels
Merlin (BBC series): More of the ArthurxMerlin fanfic verses that gets all the feels
Teen Wolf: Sterek fics have all the feels.
Fushigi Yuugi: I spent a Christmas holidays several years ago screaming at the TV and threatening it if Miaka and Tamahome didn't end up together at the end.
Kingdom Hearts
Journey
Then there a bunch of novels too (Nightrunners series and Tamir Triad by Lynn Flewelling, Avalon series by Marion Zimmer Bradley, and random campy gay novels).
Oh, and when Ash tried to leave Pikachu behind early on in the Pokemon anime. THE FEELS!
I get feels and cry a lot during a lot of stuff. I am an excitable person.
