You and baju had a complicated relationship. Maybe a love hate relationship? Well both had complicated feelings to each other. You could accept the fact that you liked baji but him? Well let's say he wasn't good at expressing and progressing his feelings especially if it was something like love that he always ran away from it and thought it was useless. So what would happen if he finds out that he has some feelings like that for you? Would he Express it like a normal person? Of course not. No. Instead, he starts to treat you weirdly and coldly. And when you asked him frustrated that what was his problem he just snapped. "You you are my problem before you, my life was great... everything was exactly how i wanted but when you showed up in my life you ruined everything...my happiness...my life...you ruined my life THAT'S THE PROBLEM"
