I dont really care about the main leads as everyone knew who she would end up with, but why would u hurt seojun so much, it doesnt really make sense to me as he stayed with her for three years, he graduated with her, celebrated her birthdays, took care of her while suho wasnt there, they didnt even date for that long but seojun was the one who had to give up on his love. suho decided to breakup because "it would he hard on her" i mean this point itself is not understandable for me. Fine that she ended up with suho but they could have given seojun a better ending! he wasnt even at the wedding! I loved the show, the cast for the best, no one could have done it better, but the ending really ruined the whole show for me.
