As every human being is uniquely different from each other, a straightforward answer cannot be given to this question. I'll try to give out a general response.
If you are attracted to a particular boy, being friendly with him would be the easiest way to start off. If he is positive, he'll never neglect you as a good friend. Then be gradually closer to him, and study about the attitudes he likes. Try to behave in that way as possible (but always remember to control your self-discipline). With time, the particular guy would ask for love.
In the case that he is not positive at you, the task would be not easy. Then you may try showing that you would be important to him in his life in some way. Make sure, not to things which irritate him or his feelings, as you are going to 'tune' them for you. If if is still not okay even as a friend, never give up, you may try again. Don't stalk him, otherwise if might think you as 'just another girl'.
While talking and being near to him before the relationship, there are several facts that would favor you. It is a common fact that girls like to talk with boys face to face. Unlikely or unfortunately, boys are mostly not like that, they tend to be emotionally close to the girls of their interest when they are by aside (but near). When you are doing stuff together try to balance both of your interests (as a couple you would hope to be). Do not try to impress him unnecessarily always and beware, not yourself too, unless he'll think that you're selfish.
when a boy see what he like
be very polite to the girl. being a gentleman is the best advice for a boy to a girl.
You don't 'make' someone love. It develops and grows over time.
simply move on.
boy agremented that in future he could nvr fall in true love but after that he will again felt in true love
You cannot force someone to love you.
You don't and cannot 'make' someone fall in love.
Just go up to her and claim your love.
It depends whether the boy is the type of boy to love largely and whether the girl is the type of girl to love largely. But the main dependant is: whether they are really in love and how deeply in love they are....!
No. If you could, it would (and should) probably be unlawful, as you're not allowed to exercise arbitrary control over somebody else.
Keep going for your love. Even if its a girl or a boy, keep going.... Make her or him like you.
That sounds too much like a movie. Well the girl is in love with a boy. But the boy is in love with another girl. If I were the girl, no matter how much it hurt, if I loved him enough I'd want what was the best for him. And for him to be happy. I'd let him go and be happy with the other girl.
