Hi Elle and welcome! And congrats on the long engagement even if you don’t have a date set :)
Having your fiancé knowing some Japanese must be such a blessing as well as having fellow friends learning. Hopefully they can all keep you motivated and make learning that much more enjoyable! I think you’ll find the grammatical differences quite interesting. I know that my English grammar skills Improved immensely once I understood French so I’m sure Japanese will have a similar effect (not affect right? I always screw that one up. Lol).
Anywho, just wanted to wish you a warm welcome and best of luck with your studies!! :)
