can someone explain chapter 2 please 😭😭

my personal interpretation is that kobayashi (light hair) only really had interest in the other boy because of his tragedies. he pays attention when he gets bullied, he thinks him falling out the window is beautiful, he gets bored when he comes to school with short hair and a smile. that's why you dont learn the other boy's name... all kobayashi cares about is his sadness

that makes so much sense you’re such a smartie thank youuu

ur so sweet!! no problem <3
