Maybe Candy switched sides because Hajun's dad, Professor Park, is actually a good man with no ill intentions and was only used?

If I remember correctly, his actual mission was getting information about Professor Park and, if it gets so far, killing both, son and father. Or at least capturing them. Now that their agency basically betrayed them, it would make more sense for Candy to switch sides and watch over Hajun's dad. (≖_≖ )
Jooin, sweetheart, being a hypocrite isn't of much help. Still rooting for your happiness, though. Now that Yahwi is actually trying, I really hope he turns out way better than before because Cain still gives me the creeps. Lol.
