You clearly didn't read the manga if you think their relationship is anything but platonic/familial（￣へ￣）
I know the ending doesn't show any wedding of them, but it doesn't mean they will not married in the future. ╮(￣▽￣)╭
I really think asirpa has a feeling for Sugimoto. She is not really a child, she is independent and being in that era, the age that considered a woman can married is younger than nowadays. If you refer to the epsd when they met asirpa's hutchi (grandma), her grandma also said she is at the age to marry someone. So if you guys think they have like a sibling relationship, I don't think so. Please watch and read before comment
