You can make a guy think of you day and night only when you’ve gotten under his skin. He must be so absorbed in you and with you that he can’t stop thinking about you all the time. You will have to invent really wonderful ways to make him think of you.
The way you look and dress
The way you look and dress is the most important thing in capturing a man’s fantasy. You must look overwhelmingly attractive and unforgettable. Your image will be embedded deep in his mind and he will continue to think of you day and night.
The timbre of your laugh
When your laughter resonates through the air, it is sure to leave an impact on his mind, resonate with his thoughts and remind him of you. Every once in a while, when he hears a laugh, he will remember your laugh and the happy sound it carries.
When he knows how understanding you are
Every time he is faced with a problem or needs to talk about something with you, he will remember you and how understanding you are when he has something to say to you. The patience and understanding you show make your man think of you day and night.
Your care and concern
Along with his understanding and patience, he also shows a lot of care and concern for others. You are helpful and do your best to keep your man happy. You try to keep peace and quiet around you and help create a positive atmosphere around you.
the expression in your eyes
The expression of your eyes, the brightness and the laughter make your eyes shine with the love that it contains. This is something your man can’t forget. Every time you look at him or he looks into your eyes, the expression he sees remains sublime in his mind.
the fragrance of your body
Your closeness leaves your guy totally overwhelmed with the fragrance of your body. You wear a perfume that haunts him throughout the day and makes him think of you day and night. Any other person with the slightest hint of a similar perfume makes him remember you.

The tone and love that your voice carries is incredible. He can always feel the love you have for him, even when you talk to him about things that are far from talking about love. Your whole tone and volume are so infectious with love that he can’t help but think of you day and night.
