In a way, I feel like this is sort of the brother's fault for not explaining anything. Shiro walked in on an odd and unexpected scene when he was only 14/15, of course he'd be shocked. But instead of the brother sitting him down and kind of explaining the whole situation and making him understand, he barely said anything and let Shiro come to whatever conclusions he wanted.
That's probably why Shiro was in denial so much about his feelings/sexuality, unlike his friend. So basically I'm not blaming Shiro for being the way he is ╮( ̄▽ ̄)╭

I feel like all those creepy hallucinations that Jesse had about his mother throughout the manhwa, may have been something that happened to Law but he somehow inflicted those memories on Jesse using Moritat...
Could be wrong tho ╮( ̄▽ ̄)╭

i've also wondered that too. There's also a scene where Law is talking about "his" hemophilia, and says his father must have had it, because only his clothes were soaked in blood, but the illustration showed the mother's gown all bloody. Now we know Jesse has hemophilia, so I figured it was something like your theory and not a translation error.

I don't really know why everyone is hating on takaya. He didn't know that his friend was gay or that he was in love with him. I'm still waiting to see how this all plays out (●'◡'●)ノ
Besides I kinda wanna see what happens with the senpai and his sister. Although they probably won't end up together cuz this is a BL manga ╮( ̄▽ ̄)╭
Imagine how incredibly odd and awkward it must be for the older brother to walk in on his younger brother and son doing the deed. can't handle the awkwardness ┗( T﹏T )┛
