Kazuya tries to clear the misunderstanding Chizuru is under, all while enlisting Sumi's help to get her a fitting birthday present.
Sorry if I've made things awkward, 
but you don't have to walk on eggshells.
أعتذر إن عكّرتُ الجوّ، لكن لا داعي للتوتّر
Perdona si te incomodé,
pero no te preocupes.
No tienes por qué andarte
con pies de plomo.
C’est gentil de vouloir me ménager,
mais c’est inutile.
Mi dispiace averti messo in difficoltà.
Desculpa se te deixei desconfortável.
Não precisa pisar em ovos comigo.
Извини, если напрягла этим вопросом.
