Character Arc
Yuki Itose is the heart of A Sign of Affection, a kind and observant university student who has been deaf since birth. She moves through her days with quiet grace, communicating through sign language, lip reading, written notes, and her phone, and she is supported by close friends who have learned to include her. Though gentle, Yuki is far from passive, and the series carefully centers her point of view so audiences understand both the everyday hurdles she faces and the rich inner life she carries.
Her world widens when she meets Itsuomi Nagi, whose open curiosity makes her feel seen rather than singled out. Falling for him pushes Yuki to confront her own shyness and to articulate what she wants from her future, her studies, and her relationships. Across the season she grows more confident in expressing herself, whether that means standing up to overprotective figures in her life or taking the first brave steps toward Itsuomi.
Yuki's arc is ultimately about agency and self-trust. As she and Itsuomi learn each other's languages, both literally and emotionally, she discovers that connection does not require her to change who she is. The story treats her deafness as an inseparable part of her identity rather than an obstacle to be fixed, and her quiet strength anchors the romance with warmth and authenticity.
