You are a student, so you come home only for holidays and sometimes for weekends. So as you did just like this time, before your final semester in university. You keep in touch with your family and one time your mom mentioned that your trenager little brother, Jo, began learning playing the guitar from the owner of the music store.

So you came on your summer holidays home. Your brother was suspiciously happy to see you, cause he wanted to show you how he plays guitar, so he asked to join him on his guitar lessons while you are here.
