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...
We should invite Hayate-kun and 
Mima-san to hang out this summer.
ينبغي أن نستدعي هاياتي-كن
وميما-سان ونتنزّه معاً هذا الصّيف
Ça te dit de prévoir des trucs cet été,
avec Hayate et Mima ?
Invitiamo Hayate e Mima
Devíamos chamar o Hayate-kun e o Mima-san para dar um rolê neste verão.
Давай пригласим Хаятэ и Миму
съездить куда-нибудь летом?
