I'm looking for a very romantic anime with Gerdub, I've been through everything on netflix and I'm looking for something new?
Tonikawa (Anime on Demand, Chrunchyroll)
rascal does not dream of a bunny girl senpai (+ film) (Wakanim with Ger Sub, Animax with Ger Dub (Animax actually costs but you can also get a free trial subscription)
Horimiya (Wakanim)
Higehiro (Crunchyroll, Anime on Demand) simulcast
the quintessential quintuplets (Chrunchyroll, Anime on Demand)
My teen romantic comedy snafu (Anime on Demand, Chrunchyroll)
wolf girl and black prince (Anime on Demand)
Orange (crunchyroll)
Tsukigakirei (Crunchyroll)
A silent voice (Anime on Demand)
Hmm so i'm not sure if the 1st anime is romantic but yia
(now only know 2 out of my head)
1. Violet Evergarden
2. Your name
Maid Sama
Clannad
Kare Kano
Wolf girl and black prince
Vampire Knight
Paradise Kiss
Violet Evergarden
As the questioner sounds like, it is a she and all girls love Mais Sama. ^^
I would add Fruits Basket and Ouran High School Host Club, even if they aren't sad.
So I would also say your lie in April, well that's just a bit sad, I would say your name and the anthem of heart. (It's all on Netflix)
