A Sign of Affection manga volume 4 features story and art by Suu Morishita.

Yuki, a deaf college student who’s led a relatively sheltered life, has just taken a huge step: She’s got a boyfriend! And he seems like a keeper: Itsuomi is a multilingual globetrotter who works hard, and he’s a knockout, to boot. Yuki can still scarcely believe that Itsuomi so casually asked her out, and she can't help wondering - when will Itsuomi start to open up to her about his past, and his dreams for the future? Is he dating her on a whim, or is their romance real?
