Myongi and Seonho are high school classmates who meet again years later during a class reunion.

Hyperventilation is an 18+ Korean BL anime series with six short episodes. The protagonist used to be a social outcast in high school due to his lung condition, causing him to hyperventilate all the time. He formed a connection with the popular class president, who showed compassion towards him. Years later, they meet again during a school reunion, rekindling old feelings between the former classmates.

I'm impressed with Hyperventilation, a breathtaking love story that really hits the mark. The narrative is riveting and wraps up elegantly in just fifteen minutes. Although the art quality is inconsistent, this anime maintains a beautiful atmosphere that highlights the delicate emotions.

Popular and sociable, he is almost the exact opposite of Myongi in their personalities. Sunho is also a stellar athlete with a ripped body and rock-solid abs.

Hyperventilation Anime Review


Anime Review Score: 8.4

Myongi and Sunho share an intimate kiss.

Hyperventilation is a stylish and elegant BL series that tells a simple love story in fifteen minutes. This anime achieves a lot in a short amount of time, building palpable sexual tension between the main characters. Their interactions are compelling and keep you intrigued to learn more about the relationship. Best of all, Hyperventilation is rich with exquisite ambiance, using colours, lighting, and visual cues to cultivate a sexy atmosphere. The results are stunning, taking my breath away with how smoothly all the elements come together.

The anime begins at a high school reunion, where old feelings reignite between two former classmates. Later, there are flashbacks of their time together as teenagers, offering insights into what transpired between them. Each episode reveals a new dimension to their relationship, unfolding layers upon layers to form a complex dynamic. Despite the simplicity of the narrative, Hyperventilation feels thoughtful, sophisticated, and emotionally nuanced. The well-crafted plot is presented by an artistic storyteller, conveying a cohesive message in every scene.

Hyperventilation features a captivating romance that gets my heart pumping. The more I learn about these characters, the more compelled I am by their chemistry. The sexual tension between Myongi and Sunho builds up like a crescendo, which finally unleashes in a sizzling scene. It should be noted this 18+ anime has explicit encounters, not shying away from physical intimacy. Yet, the sex is merely treated as part of the story, so any eroticism doesn't overpower the plot.

I go back and forth on how I feel about the art, which varies in its consistency. Some scenes are drawn better than others and the same quality isn't maintained throughout the anime. At times, the characters don't look particularly appealing with their sharp angular lines. However, Hyperventilation can appear gorgeous when it tries, showcasing atmospheric visuals that help to accentuate the story. By the way, the epilogue special looks sensational, making me wish that's the art style used in the main series. 

Hyperventilation is limited by its short length. The story gets told excellently in fifteen minutes, but it couldn't hurt to add more content, expand on the characters, and build upon their romance. Nonetheless, this anime makes a positive impression in its current state, including a lovely conclusion and a beautifully drawn epilogue special. Overall, Hyperventilation is an outstanding product in the BL genre, highlighting a successful love story with sensitivity and flair. This impressive series is a perfect example of indie excellence.

Sizzling romance

The characters share a sizzling romance. This anime does a wonderful job portraying a sexy love story that gets my heart racing.

Decent artwork

The artwork lacks consistency in some scenes and the characters don't always look appealing. However, this anime can look really beautiful when it tries.

Happy ending

Hyperventilation has a happy ending that leaves me very satisfied. I just wish the anime was longer and could have expanded its universe more.

Beautiful style

This stylish anime is rich with ambiance. This stylish anime series uses colour and visual cues to create a beautiful ambiance.


Hyperventilation might be short and simple, but the sensitive love story is elegantly told. The complex relationship dynamic between the characters keeps you intrigued until the end.
