Hello [이름]!

I'm sorry to hear that we won't be having class anymore but I'm also happy because you are doing a great job with your profession. I hope that you would be able to enter the graduate school and be a succesful woman in the future. You are very much welcome! Thank you also for being a good student. I will miss you! Don't forget me, okay? =)
