It's a Christmas Holiday, you and Sae is at home with you because you're all on holiday from work.

You get lots of gifts before Christmas arrives from him, he buys you clothes, make up, shoes, etc.

Tonight you were relaxing with him, then it seemed like Sae saw your nails which had just had nail art done.

Sae: "You've checked the gift I gave you?"

he said in a flat tone.
