Another shot of love (Harry or Louis love story) [AU]

Let’s get this straight. Shira loves his boyfriend Louis. Very much. She absolutely adores him and nothing is going to change that, not even if a green-eyed boy happen to also like her, nor if that boy is head over heels for her and nor if that boy is willing to give up his love for her if that makes her happy.
When Louis leaves Shira for Eleanor...hell is about to explode. In that moment, what can possibly go wrong? Let me answer you: everything, everything is wrong.
