The death of a loved one

Your at home reading with your little brother that is until some people come knocking on your door asking how old your brother is and saying he HAD to join the war. He was happy that he was old enough.
One day you get a message saying your brother is dead. You cried your eyes out when you got that message. A young man slightly older than you comforted you and he was happy to help you.
3 weeks later you never even see the boy after that day and you decide to join the war to help as a nurse or actually fight in the war (haven't decided yet on that lol xD ) You meet the boy again and fall in love
