if あなた need もっと見る just ask

It's tough cause I've already seen most of yours または ones already posted. I'm not sure if any of these are what あなた are looking for but might as well give あなた some options:

Lovely Complex- もっと見る of a comedic romance but it has its cute moments

Fruits Basket- Not that overly sweet または sad but it has some moments. And might be too comedic

Natsume Yuujinchou- This is not short, several seasons long and it has it's adventure moments but man most episodes hit あなた right in the heart. It's not a romance though. But it's one of the sweetest animes out there. Slow paced アニメ without being boring. It is my number one お気に入り anime

Otome Youkai Zakuro- Once again, just has its cute moments. But 全体, 全体的です there is mainly action and is prob the least feely アニメ on my list. But it has one of the sweetest couples Susukihotaru & Riken (but they are a minor couple)



Song is one of Natsume Yuujinchou's endings. It's just so pretty
