do you think it has real friendship between different gender!

Yes, you are right, it isn't easy to start a relationship based only on the frienship between a boy and a girl, and yet I think it's possible. Difficult but possible. Why to set a limit to human possibilities? Everything is possible, so I think you'll be able to start a friendship with a boy.

Here is a definition for friendship: Friendship is a type of interpersonal relationship that is found among humans and among animals with rich intelligence, such as the higher mammals and some birds. Individuals in a friendship relationship will seek out each other's company and exhibit mutually helping behavior. Here is a definition for love: Love has many meanings in English, from something that gives a little pleasure ("I loved that movie") to something one would die for (patriotism, pairbonding). It can describe an intense feeling of affection, an emotion or an emotional state. In ordinary use, it usually refers to interpersonal love. Probably due to its large psychological relevance, love is one of the most common themes in art. The majority of modern movies have a love story and most pop music is about love. I think it would be a shame to pass up either because of gender.
