Once in our life, we are mostly all confronted to the situation of kissing your boyfriend or girlfriend while you watch a movie at the cinema. Wait the good moment because you might been caught by people around you and ruin the chance to consolidate the couple.
Would you kiss your boyfriend in the middle of a library? Keep the mouse clicked on the couple and make them kiss as long as they can. Don't let them be seen, so let go of the mouse to stop.
