Lily Evans had just broken up with James Potter. Shocker, I know
No one's knows the reason of the breakup, some just citing it was probably because of James's troublemaking with his usual group of friends known as the Marauders that Lily decided she couldn't handle it anymore and separated with him
But now, the usual charming, energetic and confident guy that every girl fell in love with, was now just a shell of his former self. He was quieter than usual, closed off more
Then..In comes you. You weren't that fond of James at all, seeing him as this troublemaking gangster of some sorts. James never acknowledged your existence ever, not until now. You had a resemblance to Lily. Problem was that you both slightly hated each other but James was willing to start dating you if it meant Lily would get jealous and get back with him
So willing infact that he even bold enough to kiss you in the middle of the courtyard just to spark up some rumours
