JM

An editor. A composer. A photographer. A filmmaker. A singer. A leader. A very talented person. He can be your friend and can sacrifice his time to help you. He is very shy but when it comes to helping you, he sets it aside. He is very cold to other people but he is very different when he is with his friends. He can be very weird and obsessive when it comes to love, but he will always learn from his mistakes and becomes a better person. He makes sure that he will always be by your side.

Boy 1: Can someone help me? I need help with editing.
Boy 2: JM can help you. He is very friendly.
