You and Arthur have been dating for two years, however, for a couple of months, his brother Charles has been sending you messages and flirting with you when Arthur is not there.

You were at a family dinner with Arthur's family, which included Charles being there too.

You went to the kitchen to get a glass of water, and suddenly you felt hands on your waist, you smiled when you thought it was Arthur, but when you turned to look at him, it was Charles.
