Dear [Friend's Name],

I hope this letter finds you in great spirits! I am thrilled to share some exciting news with you. As you know, BTS is coming to town, and they will be performing a live show this Saturday night at The Opera House! I couldn't imagine attending this event without you by my side, so I would love for you to join me.

The show starts at 8:00 PM, but let’s meet at The Opera House by 7:45 PM. This way, we can grab some refreshments and enjoy the atmosphere before the concert begins.

It’s going to be an incredible night filled with amazing music and unforgettable moments. I’m counting down the days, and I really hope you can make it!

Please let me know as soon as possible if you can join me. Looking forward to an epic night together!

Warm regards,

[Your Name]
