you were recently assigned to help out a classmate who wanted to learn more words since his inherited technique prevent him speaking things. he wanted to learn at a quiet cafe which led you to your current position.

you sipped on your drink as you listened to your 'student', whose name was toge, speak a bit

"kelp." he said, the fabric on his collar ruffling a bit as he spoke. according to your notes, kelp meant 'hello' or any other type of greeting.
