Tangled and twisted

Two brothers who love eachothers but don't show it. Elder one, careless, bad boy, heartless, selfish and younger one, compassionate, loving, considerate and selfless.

What will happen when they fall for the same girl ?
Who will back off for the sake of the other ? Or will they fight for her ?

What would be the outcome when, they are over possessive for her and can't share her with anyone else ?

What would be the magic which will let them at ease even at the thought of sharing the love of their life with their own brother ?

How are they gonna survive the tangled and twisted situation ?
