Great love story from being friends and now real love couple. It's normal fighting or having a quarell with your boyfriend and the best part is that because you were friends first, you understand each other more so resolving problems with him is much easier. So, I hope and wish that you both will end up into marriage one day. Not now, because I know Hyunjoo is still a student but maybe a few years later. And Congratulation on making it to the 930++ days on being a couple. Best wishes from me.
