Hm... nah, I still can't like it, even if I can somewhat understand his motives. Itsuki should have maybe taken notice of his plight, but in no way could this ever justify what he's trying to do. He really was trying to emulate his brother's actions, and I am not liking it.
At the very least, cracks are already starting to show. He simply can't keep up this perfect image, and his brother simply isn't going to take this laying down.
