Well, too bad, Wistash. This isn't "The Emperor Reverses Time". And honestly, your reasons for wanting to turn back time are... incredibly selfish. The Emperor in that story wanted to reverse time because he regrets making her live a life of misery, deprived of her own will and freedom, that she became a mere puppet without a soul. He wanted to reverse time to SAVE her from that life, and wants her to simply be happy and free, even if he's not the man for her.
You, you are wanting to reverse time not for her sake, but for your own sake. You wanted to isolate her so that she would always stay by your side and love you and only you. Your regret is purely shallow. You still don't respect her, still don't bother to take a good look at yourself over how you screwed up.
I'm glad that Joachim mocked you. Sadly, it seems that you have a long way to go before you learn your lesson.
But... you could be worse. You could be like the ex from "Father I Don't Want to get Married", where he is just an arrogant prick that literally thinks that she's trying to get his attention and is pissed that she is going for another man after breaking up with him, despite how he literally told her to never appear before him. So great job, you're not AS bad as him, but still plenty trash.
