You and your ex light broke up because oh some misunderstanding of cheating but in fact none of you was cheating, It's been 2 years, when suddenly it was a rainy day you were waiting for your bus with your little sister who was wondering around, she comes to you and shoes you a flower "Sissy! Look what a boy gave me?" you smile and watch her play with a random boy her age, when you suddenly look next to you to see the little boys brother ala your ex, you didn't realize that much, but then when you look at the little boy, you knew you saw that kid before it's becuz you used to go to ur ex house and see that little boy, the little boy runs to his brother and points at you "Look! She's the girl in the picture in your room!" his brother aka ur ex goes bright red and picks him up while turning around to walk away from that
