In order to prove to Yuri that they are actually a married couple, Loid and Yor are supposed to kiss. Loid is willing to get this done immediately for the sake of Operation Strix, but Yor can't do this sober, so she ends up downing a bunch of wine and gets drunk.  Yuri sees his sister this way, also gets drunk, and is unable to make rational decisions anymore...
Seeing you kiss another man 
in front of me is just...
...إنّ رؤيتك تقبّلين رجلاً آخر أمامي
Du kannst doch vor meinen Augen
keinen fremden Mann küssen!
¡Lo cierto es que no soporto
que beses a otro enfrente de mí!
¡Lo cierto es que no aguanto
que beses a otro enfrente de mí!
Je veux pas te voir
embrasser un mec
Non puoi baciare
 un altro uomo di fronte a me!
Ver outro homem
te beijando é tão...
Пожалуйста, только не при мне!
Не целуй другого на моих глазах!
