Yeah me too. For Iwaki and Katou to care for each other that much and not forgive anyone who lays a finger on each other, they DEFINITELY know the pain of seeing a loved one hurt. And I also don't think they would have let Yousuke get hurt like that. How can you justify protecting your kid's dream while letting your kid get hurt (maybe scarred for life)?! Their idea of parenting is so messed up. It's a big NO for me too.
I doubt we can call it 'parenting' at all bc Iwaki is still trying to get used to the idea of being a father while Katou was sort of troubled with that idea. It was just bad judgement as seniors in industry on both their part when they both have been through same experiences!
The situation with Shou is so pitiful! I can understand that nothing was confirmed back then and they aren't experienced with upbringing a child. But the way 4 grown-ups knowing the situation never warded Shou off that path is unacceptable! I can't believe Iwaki and Kouta not even for once said sleeping with someone for work shouldn't be something he ought to do at such a young age! If it had been Yousuke would they still overlook it? No, ofc not! This is so disgusting! I can't help but hate Kouta and Iwaki for how they treat Yousuke and Shou with such partiality! #－.－)
