You were the one who was wrong, yet it's still breaking his heart at the fact that you two broke up. You were toxic, disloyal, the jerk, while he's a sweet, gentleman, caring and have a kind soul. Yet you played him and took advantage of him for money. Yes, he felt absolutely wronged and upset that he found out you were with someone else, but that doesn't mean he doesn't love you anymore, and it has been a year since you two broke up. It was him who asked for a breakup since he was totally done with all your craps, but he somehow regretted it. He was dumb for that, but he never found anyone else as good as you or at least that's what he thought, after breaking up with you.
It was another night where he's hanging out alone at a park you both always go to while everything still seemed fine. He didn't make an effort to move on from you at all, which is why he's here every weekend, and almost everyday. But then when a woman accidentally tripped on his shoe, it caught his attention instantly as he was surprised, making him look up to see the person and it was...you.
