You and Yui are neighbors but also lovers. Even though you're now both working, your relationship hasn't really changed and you're both living happy lives. One day, you both are celebrating your anniversary and a certain game leads you both to a huge turning point in your lives.
Thank goodness! I guess it 
was worth all the trouble.
حمداً لله! أعتقد لم يذهب العناء سُدى
Gott sei Dank!
Dann war es den Aufwand wert.
¡Qué bueno! Valió la pena esforzarme.
¡Qué bien! Valió la pena esforzarme.
Ouf ! Je regrette pas
de m’être donné du mal.
Meno male! Allora ne è valsa la pena.
Que bom! Valeu a pena me esforçar.
Вот и славно! Мои старания не прошли даром.
