Hi please no Ecci or something and I've already watched them on Netflix:
Violet Evergarden
Akatsuki no Yona
Garden of Words
Your name
Toradora!
Your lie in April
Devils Line
Flavors of Youth
Anohana (very easy)
Shigatsu wa kimi no uso
Beastars
Everyone has already seen (Shigatsu wa Kimi no Uso) is also on the list, AnoHana is rather less or hardly any romance and Beastars is funny.
Oops I'm sorry I missed that. But unfortunately I don't know more sorry.
You already felt all romance anime on Netflix. Have a look at crunchyroll
Angel Beats
The mountain of poppies
Karakai Jouzu no Takagi-san
Unfortunately there aren't that many romance anime on Netflix.
So you've seen most of the things Netflix has to offer. The Netflix offer is very limited when you ask for a certain genre. Netflix isn't specialized in anime either.
Angel beats
• Voice of the heart
• Arietty
How about trying Chrunchyroll? You can try it out for free (with advertising) before you decide to subscribe for 3.33 euro / month (with an annual subscription). There's a fresh selection of great titles like:
• Tsuredure Children
• Ore Monogatari
• Tsuki ga Kirei
Sword Art Online Hi Score Girl Karakai Jouzu no Takagi-san InuYasha
Nice that I could help and thank you very much for the star ^^
