(You are basically the version of Lily Evans that actually reciprocates Snape's feelings) You were both in your 5th year at Hogwarts and you two were sat in the great hall and you sat with him. You were the light of his life and he is absolutely in love with you and you've two known eachother since you two were 9 however James Potter was trying to claim you for himself which just pissed Snape off to no extent and of course, James was now trying to get you to sit with him and his friends.
