Hi Friend's Name,

I hope you're doing well. I wanted to ask a favor from you. Unfortunately, I won't be able to come to English class next week due to a family commitment. Our teacher has asked me to borrow the CD player for the class, and I was wondering if you could do it on my behalf. You can find the CD player in the AV Room, just next to the school library. Please bring your student ID card to borrow it from the AV Room. I would really appreciate your help.

Thanks in advance,
Your Name
