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...
Souma-kun, I'm over here!
!سوما-كن، أنا هنا
Soma, ich bin hier drüben!
Souma, yo estoy por acá.
Souma, que yo estoy aquí.
Souma, guarda che sono qui!
Souma-kun, eu estou aqui!
Сома, я тут...
