Probably 'Vampire Knight'. It has a large fan base. The love story in it is very appealing as it combines the allure of vampires with the classic theme of a love triangle. The characters are well - developed and the story has a lot of twists and turns that keep viewers engaged.
Well, 'Fruits Basket' has a really touching love story. Tohru's relationships with the Sohma family members, especially Kyo, are filled with love, growth, and acceptance. Then there's 'Sailor Moon', where Usagi and Mamoru's love is iconic. It's a story of a princess and her prince, but with a lot of magical girl elements. And 'Spirited Away' also has an underlying love story. Chihiro's relationship with Haku is one of mutual protection and a budding, innocent love.
'The Garden of Words' is also quite unique. It's a short anime that focuses on the relationship between a high school boy and a mysterious woman he meets in a garden on rainy days. The plot is slow - paced and very much centered around the beauty of the rainy season, the garden, and the developing feelings between the two characters. It doesn't follow the common action - filled or high - school - drama - like plot of many other anime love stories.
'Fruits Basket' is quite popular. It's a story that has a love aspect along with elements of friendship and self - growth. Tohru Honda, an orphan, lives with the Sohma family. She forms relationships with various members, especially Yuki and Kyo, and there are love triangles and complex emotions at play.
In my opinion, 'Blood Lad' is relatively loyal to the manga. It captures the essence and atmosphere of the original manga well. Some small changes are made to fit the animation format, but they don't significantly deviate from the source material.
Well, 'Fruits Basket' is quite popular. It combines elements of love story with a unique supernatural premise. The main character Tohru Honda gets involved with the Sohma family, and among the many relationships that develop, there are beautiful love stories, especially the relationship between Kyo and Tohru which is full of growth, acceptance and love.
Definitely 'Sailor Moon'. The love story between Usagi Tsukino and Mamoru Chiba is a classic. Their relationship develops over the course of the series as they fight against evil together. Usagi's transformation into Sailor Moon is also intertwined with her love for Mamoru, which makes the story really engaging.
I think 'A Silent Voice' is quite heart - wrenching. The main character's journey of self - loathing due to his past bullying actions and the deaf girl's struggle with isolation and acceptance make their relationship really difficult. The moments of misunderstanding and the slow process of them trying to understand each other can bring tears to your eyes.
Definitely 'Your Lie in April'. It's extremely popular due to its stunning art, beautiful music and the touching love story between the two main characters. The story of how they influence each other's lives is really captivating. 'Clannad' is also very popular. It has a long - running story that develops many different relationships and the love story in it is very relatable. People love it for its emotional depth.

A very popular one is 'One Piece'. Luffy is the OP MC. While the love story aspect isn't as central as in some other anime, his relationship with Boa Hancock has elements of a love story. Hancock is in love with Luffy and it adds an interesting dynamic to the story, especially considering Luffy's rather oblivious nature to her feelings.
