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...
And you shouldn't wear it like it belongs on you.
ولا ينبغي أن ترتديها
Wenn du ihn auch so selbstverständlich
trägst, als würde er dir gehören!
Y tú no te la pongas como si fuera tuya.
Y tú no te la pongas como si fuera tuya.
Et toi, ne le porte pas
comme si de rien n’était.
E tu non indossarlo con tanta naturalezza.
Então vê se não veste
tão bem na próxima.
А ты не носи его так, будто он твой.
