If you’ve spent any time in the anime community over the last few years, you’ve probably noticed a shift. People are tired of the "will-they-won't-they" trope that drags on for 300 chapters without a single handhold. That's why A Sign of Affection (Yubisaki to Renren) felt like such a massive breath of fresh air when it hit screens. It didn’t just give us a romance; it gave us a sensory experience that changed how we look at communication in animation.
Honestly, the A Sign of Affection anime is kind of a miracle of production.
Usually, when a studio adapts a hit manga, they focus on the big "sparkle" moments. But Ajiado, the studio behind this one, did something much harder. They focused on the silence. Since the story revolves around Yuki Itose, a university student who has been deaf since birth, the sound design isn’t just background noise—it’s a narrative tool. You’ve probably noticed how the audio muffles or shifts when we see the world through her perspective. It’s intentional. It’s brilliant.
What Sets This Story Apart From the Usual Shojo Fluff
Most romance anime rely on misunderstandings. You know the drill: someone hears half a sentence, runs away crying, and they don't talk for six episodes. A Sign of Affection basically tosses that script in the trash.
Yuki and Itsuomi’s relationship is built on a very specific kind of directness. When Itsuomi, a multilingual world traveler, meets Yuki on a train, he doesn’t treat her with the "fragile doll" vibe that many stories fall into. He's curious. He wants to enter her world. That’s the core hook. It’s not about "fixing" someone; it’s about learning a new language—literally and figuratively—to meet them where they are.
The Difficulty of Animating Sign Language
Let's get technical for a second because this is where the A Sign of Affection anime really flexes. Animating Japanese Sign Language (JSL) is a nightmare for production schedules. Why? Because hand movements in anime are usually simplified to save money. You get three fingers or a static fist.
In this show, the hands are characters themselves. The production team brought in actual JSL consultants to ensure that the signs weren't just "close enough." They had to be accurate. If a finger is at the wrong angle, the word changes. The fluidity of the finger movements in the anime is some of the most complex character animation we’ve seen in the genre. It's subtle, but it's expensive and time-consuming.

Itsuomi is polarizing. Some fans think he’s a bit too forward, while others find his honesty refreshing.
He’s a traveler. He speaks multiple languages. To him, Yuki’s deafness isn't a barrier; it's just another culture to explore. This perspective is actually quite radical for shojo. Usually, the "cool guy" is aloof because he’s brooding or has a dark past. Itsuomi is aloof simply because his brain is already halfway to Germany or Laos. When he decides to focus that energy on Yuki, it feels intense.
It’s also worth noting how the show handles the concept of "voice." Yuki uses a smartphone to communicate with most people, but with Itsuomi, the barrier starts to dissolve. The visual representation of her inner thoughts—often depicted with soft colors and floating text—contrasts beautifully with the physical reality of her signing.
The Supporting Cast: More Than Just Plot Devices
We have to talk about Shin and Emma.
In a lesser show, Emma would just be the "mean girl" rival. Here, she's a person dealing with long-term unrequited love and the realization that the person she wants is moving in a direction she can't follow. Then there’s Oushi, Yuki’s childhood friend. He’s the "protective" type that fans usually love to hate. He’s grumpy, he’s overbearing, and he’s clearly terrified that Yuki is being taken advantage of because he still sees her as the little girl who needed his help.
The A Sign of Affection anime treats Oushi with a surprising amount of empathy. You don't necessarily agree with him, but you get why he’s being a jerk. He doesn’t know how to express care without being controlling.

Exploring the Visual Language of Ajiado
The color palette of this show is something else. It’s all pastels, but not the washed-out kind. It feels like watercolor.
Director Yuta Murano, who also worked on Kakushigoto, uses light to signify Yuki’s emotional state. When she’s feeling overwhelmed, the world gets bright—almost overexposed. When she’s in a private moment with Itsuomi, the shadows get deeper and warmer. This isn't just about making things look "pretty." It’s about building an atmosphere where the viewer feels the intimacy of a conversation where no words are spoken aloud.
Cultural Impact and Accessibility
One of the coolest things about the rise of the A Sign of Affection anime is how it sparked interest in JSL. Much like A Silent Voice (Koe no Katachi) did years ago, this series brought disability representation into the mainstream without making it a "tragedy."
Yuki is a college student. She likes cute clothes. She hangs out with her best friend, Rin (who, by the way, is a top-tier supportive wingwoman). Her deafness is a part of her life, but it isn't her whole story. That nuance is what makes the show feel "human-quality" rather than a PSA. It’s a romance first.
Misconceptions About the Ending
A lot of people go into this expecting a massive dramatic climax—maybe a surgery or a huge fight. That’s not what this is.
The story is a "slice of life" in the truest sense. The stakes are emotional. Will Yuki be able to express her feelings? Will Itsuomi’s wanderlust pull them apart? The "ending" of the first season is more of a comma than a period. It establishes that their relationship isn't a goal to be reached, but a process of constant learning.

If you're looking for high-octane drama, you might find it slow. But if you want to see how two people actually build a life together when they start from completely different sensory worlds, this is the gold standard.
How to Get the Most Out of Your Rewatch
If you’ve already seen the A Sign of Affection anime, watch it again with headphones.
Pay attention to the foley work. The sound of snow falling, the vibration of the train, the specific tap of a finger on a phone screen. The sound team worked overtime to create a contrast between the "hearing" world and Yuki’s world.
Also, watch the hands. Even if you don't know JSL, you can start to recognize recurring signs. You’ll see "Itsuomi," "Snow," and "Love" appear frequently. The animators actually kept the signs consistent throughout the entire run, which is a massive feat of continuity.
Real-World Takeaways for Fans
- Check out the Manga: The anime covers roughly the first 20 or so chapters. The manga, written and illustrated by the duo morashita suu, goes much deeper into Itsuomi’s past and their traveling adventures.
- Support Local JSL/ASL Organizations: If the show moved you, consider looking into how communication accessibility works in your own country. Many fans have actually started taking introductory sign language classes because of Yuki.
- Appreciate the Pacing: In a world of "short-form" content and 15-second clips, let yourself sink into the slow burn. The intentionality of the pacing is the point.
The A Sign of Affection anime succeeds because it respects its audience. It doesn't over-explain. It doesn't treat Yuki with pity. It simply asks us to sit in the silence with her and find the beauty there. It’s a masterclass in empathy, and it’s arguably one of the most important romance titles of the decade.
To truly appreciate the depth of the series, look for the official "Sign Language" guides released by the production committee on social media. These shorts break down the specific signs used in key scenes, offering a bridge between the fictional story and the real-world language that inspired it. Focusing on these details reveals the immense labor of love behind every frame of Yuki and Itsuomi's journey.
