Happy Birthday, big Bro! You are my source of strength when I was an undergraduate student. I always motivate myself by thinking that if you can do well during your undergrduate years, so do I. Can't believe it's been three years since my graduation.
I don't know what to wish but I pray for your happiness in whatever you're doing. I really hope that you will take some rest because I'm worried for your health when I saw how hardworking you are.
Anyway, once again, happy birthday, Sakurai Sho
