A lot of us are gonna emerge out of our cocoons. We're gonna made it lads!

But it does surprisingly explain a lot. Kusonoki wanted to confide in the only one she could relate to back in middle school. She may not have directly spoken but she knew they had enough common interests.
Meanwhile, Keisuke would be aware of Kusonoki but sees himself as unworthy and undesirable. So he probably put down any notions that a girl would want to seriously get to know him. In a similar vein he was probably too distracted by his own thoughts and Kusonoki's derp to even realize they had common ground.
