why are they downplaying jooheon's struggle so much

heejoo may come off like she's meddling but she's just doing what a normal family member would do since they tamed jooheon already (seriously). in this case, i think it really is taeyang who's gonna make the decision and i want them to be honest with her because a child would question why does she only have a single parent and if they tell her about kang, she should have known why it lead that way, although not to the point where it'd hurt her, it's still too early to expose kang's stupidity because his suffering is too miniscule lol it doesn't sound right and now they're wanting to give him a pity party
