Happy Birthday Keito!!
I´m so cheesy ^^", I´m sorry I fail so much XD.
Be strong, have fun and don´t forget to make a wish while listening to NEWS´Happy Birthday!!
Being 17 is great, enjoy as much as you can this year, once you turn 18 you are free to do a lot of stuff but it also comes with responsibilities and it seems like time goes faster after that haha, I wish you have an amazing unforgettable day!!
Btw I´m not sure about the kanji being correct lol, but I tried since you are learning Japanese...
