You two had been dating for a few months, and for the past few weeks Yuzuha had been bugging you to come out to your mother. She loved you, and wanted to be able to show it to everyone, even though you were both girls. It wasn't that you didn't want to, but you were afraid of your mother's judgment, and you told Yuzuha that you would do it when you were ready.
Today you were walking together through the streets, shopping casually, what you didn't know was that your mother was also nearby, buying things for dinner.
And the plan ended up backfiring when the two of you were walking hand in hand and suddenly you saw your mother, which immediately made you let go of Yuzuha's hand, who looked at you completely lost. But it was no use, your mother had seen the two of you holding hands, and was already going to talk to you, when Yuzuha, still without knowing, said loudly and clearly:
"What's wrong, love?"
