He doesn't get it.

Behold as her braid phases out of existence as she turns her attention away from her book.

Meaning that if she were to stop reading entirely and go home, she would fade away completely and disappear.

That book is her lifeline. Rinnosuke does not understand this.

In case anyone doesn't know her, she's a professional female wrestler that she committed suicide due to cyberbullism at the age of 22.
A drastic death indeed.

As a wrestling fan, after hearing this and watching her matches, it's sad and devastating what happened to her.

Wrestling took a huge blow in the last few weeks.

Hana Kimura's death

Also, Shad Gaspard, who died as a hero by saving his son first.

RIP to both of them.

There's that little voice in my head saying there's probably more to this story than it seems. Either there was some form of mental illness present (likely undiagnosed), the harassment has been going on for longer than it seems, or both. In regards to both issues, Japan is extremely and horrifically behind the times.

Either way, places like Twitter are a cesspit of narcissists and assholes. Unless it's to make some form of an announcement, don't waste your time with it. And, for the love of all that is holy, if you ever gain even the slightest degree of notoriety, never, EVER engage with anyone on there.
