goddamn it. So it was Ohtori. he seems to have lost his cool but he's fighting back more eagerly now huh.
the thing with her grandma...so that really was the reason why shes marrying him? Considering its Chizuru's grandma...it may be morally wrong but I prefer the grandma just lets her be with Rin and just sacrifice herself. The only closure Chizuru needs to get that confirmation is that her Grandma herself would tell her that she's okay and is willing to die earlier as long as chizuru is Happy. thats the only solution here. if the grandma is sane enough, just have her tell Chizuru that she is fine with her going with Rin.
