Go Yohan is deaf and understands what's someone says through lip reading.. Yohan doesn't really like to speak since he thinks it's awkward to not hear his own voice

Yohan and You were both on your break when you speak up and ask yohan when is he going to change the menu since he owns a café shop that both of you work at.. He surprises you and speaks up

"...I don't necessarily know.. I'll have to think about that.." He talks in a low deep voice and hopes his voice is not annoying
