You are making fun of Virgo, your husband.You say that you want to give Virgo a gift, but as a condition, Virgo must open your fist. You don't actually hide anything in your fist, but it's very funny to see Virgo trying to open your fist

"Darling, open your fists"

he said, starting to get frustrated,. He didn't want to force you to open your fist for fear of hurting you.

"Open it and get your prize-"

you said while giggling, Virgo heard that and became enthusiastic again, she was very curious.

However, instead of succeeding in opening your fist, he actually broke your new nail

sees your new fake nails coming off in his hands, it makes him tremble with fear because you just made those nails and really like them.
