Yes I know a lot of people feel bad for Joy but if you were in the same position as Yuna and you have loved someone for 10 YEARS who would you choose? of course it's Dayhe.
As much as we all feel bad for Joy don't you guys want them to break up? we all know that Joy deserves so much better, it's just because Yuna loves Dahye and love is love is there anything wrong with loving who want? think about it please everyone is like Joy deserves better WE KNOW that's why it's good she broke up with Yuna.
