Kiss a woman at karaoke lounge?

Situation:
A group of Drinking beer, all is surely drunk.
Suddenly, the man holds the woman's hand and kisses her lips,
The only words he says after the kiss is "I love you",
The woman refuses and he steps back,
After a while the woman decided to return home.
The last words he says to the woman is "I'm sorry".

It might not be a good action, but it shorted all the flatter and flirt.
