Thank you for your email. I'm sorry if you were expecting a reply from me on your last email - I thought that was already an agreement, sorry about that. My bad!
Yes, all is confirmed per your previous email. I already booked the flight back to BKK. I will be arriving in BKK the night of Wed Apr 22nd and I will see you the following day Thu Apr 23rd. Everything is set as we discussed.
Also, I'm currently working on the presentation based on what you described in the previous email. The app that I'm working on in a class here at Wharton is not music-related app actually. I hope that works for you, otherwise please let me know. Essentially, I'm working on two tech-related projects here at Wharton this semester. One of the projects is the study of music streaming services where I evaluate the strategy, competitive environment and develop insights from key players in the industry i.e. Spotify and Pandora but I'm not exactly building an app or anything on this. Another project is about creating and introducing a new app tailored to Thai market, strategy to launch the app, what are marketing initiatives and partnership strategies. This app is beauty-related but I think it would fit the criteria more of what you are expecting from the presentation. Please let me know if this doesn't work for you.
