Convince a Shy Person to Be Your Valentine

If you have your hopes on getting a shy person to be your Valentine, you need to plan and take some steps to encourage them'

Steps

Begin well before Valentine's Day, talking to the person, treating them nicely, and giving them hints.
Talk to them about things they enjoy, and always be willing to help them if they need help, or to just listen if they have something to say.
Find an opportunity to talk specifically about Valentines, which ones you like, which ones they like, and who they might want to give a Valentine to.
Ask them if they would mind if you give them a Valentine, as this will tend to make them feel like they might want to reciprocate.
Make that person feel like they are on top of the world. Not like kissing their butt but just make them feel welcomed and make them feel good with your award winning smile and awesomeness.

Be patient, and be prepared to be let down.
Remember that shy people can be very sensitive to pushy or forward people.
A lot of times, people who come across as shy may have a deeper personality, even somewhat crazy. If you find out that someone is like this, make sure you don't make them feel uncomfortable in their own skin. A lot of times, people are shy because others have made fun of their personalities.
