A smile can charm a man.

A smile is a very powerful tool that is often underestimated. One study showed the following relationship: happiness was the most attractive expression of emotions in women, while in men, on the contrary, they were most fascinated by seriousness. Try to make eye contact with the object of your attention. Smile as often as possible, regardless of whether the emotion is directed at your boyfriend or not. In any case, this will make you more attractive in his eyes.
