Wind breaker theories

Several events occur in this chapter. It turns out Momijikawa’s grandmother will soon be leaving him, leaving him completely alone… I don’t know why, but based on this, I had an idea. What if Sakura’s past, which remains unseen, is similar to Momijikawa’s? I’ve been sharing my thoughts for several chapters about his possible relatives, adoptive family, and past, but I didn’t think about this. What if Sakura’s entire family, just like Momijikawa’s, is dead? This theory is also supported by Nirei’s words, that after hearing Sakura’s story, Sugishita began to ponder many things. Based on these facts, it seems a little likely. So, Sakura’s story could really unfold through Momijikawa, especially when some random gang, or more precisely the guy from the chapter where Momijikawa beat up some guys, goes to their leader and, out of a desire for revenge against Momijikawa, sets him on the guy. It might be that Sakura and a few others will go to his rescue, or again, everyone will be involved… although I doubt it, we’ll see.
