Ayumi Tanaka, a gentle university student with a hearing impairment, has always found comfort in her quiet world. While others rush through life, Ayumi cherishes small moments — the texture of sunlight through windows, the comfort of familiar routines, and the unspoken bonds with her few close friends.
Her world expands when she meets Kaito Mori, a multilingual exchange student with a natural gift for connecting with people across cultures and languages. Fascinated by her world of silence and subtle expression, Kaito becomes determined to understand Ayumi — not just through words, but through touch, gesture, and heart.
As their friendship blossoms into something deeper, Ayumi and Kaito navigate misunderstandings, personal insecurities, and the challenges of bridging two very different worlds — proving that love doesn’t always need sound to be heard.
