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...
You're going to treat me like that just 
because I tried to stop you from kissing him.
ستعاملينني هكذا فقط
.لأنّني حاولت منعك من تقبيله
Wenn du mir so eine verpasst,
nur weil ich euren Kuss verhindern wollte,
Si me apartas así
cuando intento evitar el beso…
Si me apartas así
cuando intento evitar el beso…
Tu es allée jusqu’à me frapper
quand j’ai voulu t’arrêter…
Respingermi con tanta forza perché 
ho cercato di impedirti di baciarlo...
Vai me tratar assim só
porque tentei impedir o beijo.
Я просто хотел поцелую помешать,
а ты меня аж прочь отбросила!
