This is just getting beyond sad. There are so extremely few attractive qualities of Shiraishi, and the story barely even mentions the ones that do exist. How long has it been since Shiraishi did anything good that any basic human who isn't a complete jerk wouldn't do? It's been at least quite a few chapters.
This is just made for [Japanese] boys to self-insert and feel good about themselves and dream about a girl doing that for/to them.
