Exactly. If you have two children, you normally love them equally, you don't make distinctions or treat them differently. Of course, you raise them according to their individual needs, just as you love each of them for their own personality, but as a parent, your love is equal, there is no such thing as loving one more or less than the other. You deserve care even when you aren't sick. Jiseong was spoiled, while Jaeyi was sidelined. By the way, I wish you good health!

No, you can’t make me feel bad for Jiseong.
Ok, he was sick, but that’s no reason to be cruel and take advantage of your situation. Because of this, Jaeyi didn't have a proper childhood, he was neglected, gave up swimming for his older brother's sake, and all because of a stupid game, Jiseong started stealing everything from him… and now he want to claim Ideum, just to annoy his younger brother, for real, who want’s to sleep with someone, their sibling has already been with, and just for a stupid revenge thing. Dude, you’re an adult, can you act like it?
