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...
So why are you always hiding it?
لماذا تخفيها دوماً؟
Warum tust du das überhaupt?
Mal schlechte Erfahrungen gemacht?
¿Por qué siempre la escondes?
¿Te da vergüenza?
¿Por qué siempre la escondes?
¿Te da vergüenza?
Pourquoi tu fais ça, d’ailleurs ?
Qu’est-ce qui te gêne ?
Perché fai sempre così?
Por que sempre esconde?
Почему ты всегда зажимаешься?
