As Kazuya wonders if his birthday gift was good enough, he and Chizuru find themselves in a crisis in the form of a boozer.
If I act weird here, 
they'll think something's up!
!إن تصرّفتُ بغرابة، فسيشكّون بوجود شيء
Je dois faire
comme si de rien n’était !
Se continuo a comportarmi in modo sospetto, 
dubiteranno di me.
Se eu agir estranho, vão achar
que tem algo de errado!
