Is it just me or they kinda forgot that Yohan was deaf by the end??? Its so sweet and all

I don't think they did Σ(っ°Д °;)っ
In the last panel, soohwa pulled on yohan's shirt to let him know someone came it bc yohan's back was turned ro the door and wouldn't be able to hear the chimes. Also, soohwa recommended his parents to speak slower so yohan could read their lips. It's all the small moments where you notice soohwa always facing yohan when he's talking that're key. This story kinda implies that people who're deaf can live normal lives and other people shouldn't treat it as a pitiful, hindering disability. If I communicated wrong info, pls let me know!

Its just that it feels like Soohwa was kinda immune to Yohan's voice now, and Yohan isn't using sign language more often.
