Am I the only one think Satoru did that in purpose knowing Shin's confused mind? I mean, he knows about them right?

For your first comment Shin and Mitsuya not done anything
as for helping him I think and I mean I only thinking yes could be he's not a bad brother or ( firend or lover Mitsuya ,that we don't know yet ) and his brother wanted to spend time with him sooo I guss it a posble unless he has other motives

I thought what Hatsune saw was the fire, since she said 'What's that..?'
But when said 'brother!', then ran into the fire, I couldn't help but think that actual, maybe, her brother is alive... Ah, I'm a little confused.

I think she's referring to the Australian flowers, since they're basically a memento of her brother. In my opinion, that's some sentimental bs right there to run into a burning house for some flowers. Maybe it's something like suicide because she felt guilty for not being able to prevent her brother's death, or she loves or likes glasses guy despite the fact he loved her brother. Either way, this part was rather cliche and unrealistic. Well, it's not like that doesn't make this manga a worthwhile read.
Damn, my highschool memories come back again. Why the hell Gamou's condition is exactly same with mine 2 years ago? Argh.
