What does "Would you like some black tea" mean in Tieba anime?

This is a very popular meme on the Internet recently. It seems to be a French script and then translated. There was a couple eating in a restaurant. The girl thought the boy was cheating, so she became hysterical and roared, but the boy just ate calmly, very calmly. He also kept calmly asking her if she wanted to drink black teaˊ_gt;ˋ, just like this several times. The script is written from the perspectives of different onlookers, but the key point is that the male protagonist keeps saying calmly: Do you want to drink black teaˊ_gt;ˋ (this expression is also very important)?

Watching too much can easily cause internal injuries. The main thing is to express calmnessˊ_gt；ˋ. . .
