To Yurika!
Thank you sooo much for your advice. How kind you are!!!
I thought about it all the time and I decided to try sagasai-jikkoiin even there's no friend. I believe that if I don't move at all, I can't never challenge myself. So I decided to join it!
But I'm very happy to meet your friend there:) Could you ask her what department she's working at?
Thank you again for your kindness Yurika!
To Yusaku!
Thanks for your comment and advice! When I thought about it for a long time, I came to an answer as a same way as you that doing nothing won't be a benefit for me. So I'll try!
