What you could do is you could do a girl in the middle that matches your character description looking really confused or needing assistance. Then have Harry and Liam on either side. Either: a) both trying to do something nice for her (one could have like roses in his hand and the other could have like a box of chocolates for example) b) both angry and staring at each other with a look that says like "she's mine" c) kissing her cheek on both sides (for example Liam on the left kissing her left cheek and Harry on the right kissing her right cheek).
Find me on wattpad @epicmoustache12 because I make covers. PM me and tell me what the main character looks like and the title. :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
