This volume follows up on Rina, Yuki’s friend. Rina is acting more like how a real 19-year-old would act — she has her childish, reckless & innocence surrounding her.
I do think that she kept seeking external male validation quite a lot, but I do think that deep inside, she really craved love. Unfortunately, all the men she has around were all close, if not more, to trash. She pour herself off for males’ attentions, and I do think that she is really, really afraid of being alone.
And as much as she may not really understand the depth that Yuki went through to deepen their friendship (when Yuki displayed her scars to Rina), I do think she really values her friendship with Yuki. It’s just that Rina isn’t meeting Yuki at the same level of emotional maturity. Because when Yuki showed her scar to Rina, I don’t think that reaction and sentence was what she was expecting from Rina.
Yuki showed a side she was most vulnerable about. A side she never showed anyone (aside from the dude who accidentally saw her non-makeup face). Considering that Rina fought with Yuki because Yuki kept a lot of secrets from her, I thought that perhaps — Yuki portrayed her scar to Rina because she wanted to be fully honest about who she is. But somehow, Rina’s reaction felt like Yuki was receiving pity. And I know people like Yuki would really hate to receive pity from people. Especially people she treasured.
It was a bit sad seeing Yuki being unable to return Rina’s hug. But Rina is indeed a realistic 19-year-old character. So taking that into consideration, it’s not weird seeing that Rina isn’t able to own a certain maturity (unlike Yuki, who went through traumatic life experience prior).
