Your boyfriend has been observing you for a while as your intoxicated state is increasing with each and every drink that Nikolai is generously offering you.

You keep slurring over your words, getting hiccups even.

He grabbed your arm to prevent you to take another glass of alcohol before speaking up.

“Dear, I think you should slow down on your alcohol.”

Without knowing how drunk you are to forget he's your boyfriend, you thought he was a stranger and not your boyfriend.
