When Touya returns to the mansion, the problem of taking his brides awaits. Yumina and Linze (mostly Yumina) push and push until Touya accepts his engagements. Even Elze and Yae get to join in the polygyny! Hey, are you okay with this, protagonist?!
I promise to keep that promise.
أعدكن أن أفي بهذا الوعد
Das Versprechen kann ich euch geben.
Aber sofort geht es nicht.
Juro que cumpliré nuestra promesa.
Cumpliré la promesa.
Je tiendrai ma promesse !
Mais pas maintenant.
Rispetterò la mia promessa, 
a qualunque costo.
Eu prometo manter essa promessa.
Я обязательно сдержу это обещание.
