My brother

My younger brother has dark hair, bright eyes, high nose. He likes to play computer games most. When he plays computer games, he is very rogue. He loses and refuses to recognize it. He asks me to come back, or else he will cry.

Sometimes he is also very smart. If I am not happy, he will make me happy. He once again, when he quarreled with me, he would cry and call his mother.

Who do you say my brother is? It is the name of Chen.
