Dear best friends 

Let me say something about my gratitude.

Thank you very much, gracias, and takk.

Without you, I'd not be happy to spend this semester.

As you know, I was the only one Japanese student at our university. 

I was worried I can't make friends with anyone.

However, thanks to you all, I could spend the spend time that I've never had.

This is the very precious memory that spending time with you all.

I will never forget the time we had.

Again, Thank you very much and see you next journey.
