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...
Or we could go a bit further out
 and visit a hot spring.
أو بوسعنا الابتعاد أكثر قليلاً
والذّهاب إلى نبع ساخن معاً
ma anche una gita alle terme
sarebbe carina.
Ou talvez um lugar mais longe,
como uma fonte termal.
Или даже съездить вместе на источники...
