Nasa's knowledge is a big help to the people around him, but even he's not sure about the list Kaname finds on the internet that describes the symbolism behind different kisses.
but he never thinks those things are 
the sole result of just his efforts.
لكنه لا يعتبر تلك الأمور نتائج خالصة
.لجهوده فحسب
bildet sich aber nicht ein,
es sei allein sein Verdienst, …
mais sans penser
que c’est le fruit de ses efforts.
ma non pensa mai che siano unicamente
 il frutto del propri sforzi.
mas ele nunca pensa
que conseguiu tudo sozinho.
но не считает это своей заслугой.
