My Girlfriend Would Threaten to Break Up with Me

“Like I said, I have something I can’t miss tomorrow. ……” “Is it more important than me?” “I didn’t say that. It’s just a concert I’ve always wanted to go to. I can go on a date anytime, but the concert is only tomorrow. ……” “Oh, okay. Make a choice. You can either go on a date with me, or I will break up with you and you can go to the concert.” “W-Wait a minute. Why are you giving me an ultimatum?” “Meet me at Shibuya station at ten in the morning. If you’re late, it’s over” I couldn’t find the energy to go after her. No matter what I said to her, she wouldn’t listen to me. —-I had already given up on her based on my previous experience.
