It doesn't sound like it's for lack of trying.

( which is... kind of what matters here. even though amami doesn't have a full picture, is still trying to get a sense for the type of person rokkun is, the fact is that he seems like someone rika places a lot of trust in. he knows that he isn't really the most suited to this himself either, so... there's a pause, and he glances away for a moment, breathing out a deep exhale before speaking up again. )

While you were away, one of her classmates died. ( in case rokkun hasn't figured that out yet. )

Even if it's not to comfort her, I'm sure she'd appreciate some company... during lunch and things like that.
