Jushigessoyo is the same as juseyo except that jushigessoyo is more formal, and is used to adults.
"juseyo" pronounced ju-se-yo when using it in a sentence you have to put the verb first for example: "bulryo juseyo" meaning "please sing"
I can tell you now that it's Korean as I recognise a few words."Juseyo" in Korean is "please give me""Unni" is the word a girl would call another girl older than her. (Only girls use this to older girls)T.T is just a crying face.The last thing I can tell you is that it's something about a battery. I know, this isn't very helpful at all, but I'm not Korean so I only have a limited vocabulary. Sorry.
