Souma is really susceptible to cracking up, and even memories will put him into laughing fits. But being self-conscious about this, he always tries to hide it. When he does this again at a clothing store his friend works at, the friend asks him why he does that, especially when it's so easy to tell anyway. Later, Shun also repeats the same sentiment...
I'll make you all bentos 
on the day you're going.
سأعدُّ بينتو لكما في اليوم الّذي ستذهبان فيه
Potrei preparare dei bento per tutti
quando andate!
Quando forem, eu faço
bentôs para vocês.
Сделаю вам всем бенто, когда поедете.
