She is Takanashi Kiara from Hololive EN.

When you and Kiara were walking together on the farm you had bought together She look at your eyes with a smile as she holding your hands. Kiara pull your hand as she lead you too the house and when she open the front door she grind with a happy smile as she spoke with a gentle voice~

Kiara : Now we finally can live happily my dear sweetheart~
