Whether you’re a die-hard romance anime or just love a good character-driven story, here are ten hidden gems from the 2020s that will warm your heart and maybe even make you cry a little.

1. My Happy Marriage (2023)

Blending historical fantasy with emotional depth, My Happy Marriage (Watashi no Shiawase na Kekkon) tells the story of Miyo, a girl born into a family that never wanted her. When she’s arranged to marry a cold and powerful military commander, Kiyoka Kudou, her life seems doomed—until love begins to bloom in unexpected ways.

Despite strong storytelling and lush animation, My Happy Marriage often gets overshadowed by more popular fantasy titles. Yet, its portrayal of trauma, healing, and genuine emotional intimacy makes it one of the decade’s most moving romances.

Why It’s Underrated: A slow-burn love story wrapped in a supernatural setting, perfect for fans of emotional depth and character growth.

2. Insomniacs After School (2023)

This gentle and introspective romance follows two high school students, Ganta and Isaki, who both suffer from insomnia. They find comfort in each other’s company while spending nights in their school’s observatory, capturing the beauty of the night sky.

With breathtaking visuals and subdued storytelling, Insomniacs After School captures the vulnerability of young love and the quiet magic of shared solitude.

Why It’s Underrated: Overshadowed by flashier romances, its slow pacing hides one of the most realistic portrayals of teen connection in years.

3. Skip and Loafer (2023)

Skip and Loafer follows Mitsumi, a bright and ambitious girl from the countryside who moves to Tokyo for high school. There, she meets the laid-back Sousuke, whose easygoing nature contrasts her structured life. Together, they navigate the awkward, heartwarming journey of self-discovery and young love.

While not a conventional romance, Skip and Loafer thrives on genuine emotional moments and slow-building affection.

Why It’s Underrated: It’s more slice-of-life than romance, but the chemistry between Mitsumi and Sousuke is so pure it’ll melt your heart.

4. Sing “Yesterday” for Me (2020)

A melancholic romance that explores post-graduation uncertainty, Sing “Yesterday” for Me (Yesterday wo Utatte) focuses on Rikuo, a college graduate stuck in limbo, and the two women who change his life—the cheerful Haru and the distant Shinako.

With its grounded tone and realistic dialogue, this anime delves deep into the messiness of adult relationships, making it relatable for anyone navigating love and life transitions.

Why It’s Underrated: A mature, nuanced take on love rarely seen in mainstream anime.

5. The Dangers in My Heart (2023)

What begins as an offbeat comedy transforms into one of the sweetest and most sincere romances in recent anime.

Why It’s Underrated: The odd premise puts off some viewers, but it evolves into an emotionally rich coming-of-age story.

6. More Than a Married Couple, But Not Lovers (2022)

A romantic comedy about an unusual school program that pairs students to live together as pretend married couples. Jirou and Akari start off as mismatched partners, but their growing affection makes for a surprisingly heartfelt and mature story.

Why It’s Underrated: A quiet love story that thrives on subtle emotion instead of big drama.

10. ReLIFE: Kanketsu-hen (2020 Special)
