British English, please
Thank you for giving me a chance to introduce myself.
My name is SeongHyun Lee. And I'm Korean.
I was born in a little country town named TongYung in 1986, and grew up in Busan and Seoul.
I came to Japan when I was 21.
I was empressed about Tokyo's modern architecture and a variety of pretty shops.
So I was decided to enter the college ICS for study interior.
I have recorded as written, though it may come of as sounding somewhat awkard. This is because the grammar in the script needs to be altered to something like:

Those edits would bring it more into line with British English.
