This manga? I used to collect manga whose backgrounds are other cultures～A young woman being married off to a boy who was 8-15 years younger than her was kinda a commonplace thing among the folks in the past. 童养媳～That woman took care of that boy as a sister, maid and wife. When the boy grew fertile, she(in her twenties) would probably be physically mature enough to give birth. Also women may have a longer lifespan than men, they possibly died in the same year~~

Lishifu @hakutaku I got to know their life for the first time from a movie adapted from this short novel: https://en.m.wikipedia.org/wiki/A_Girl_from_Hunan The female protagonist “cheated on” her toddler husband

Ghost @kuharido Yes, A Bride's story. I'm very fond of Kaoru Mori's manga. I try to collect what I can. I didn't you read it too.

Ghost @kuharido A girl from hunan sounds like an interesting story. The culture was very different back then. Marriage seemed more like business.

I have a half sibling(female) who is 10-year-older than me~ One-child policy wasn’t enforced well after 1990, in my class in highschool, some students have one sibling. http://i.imgur.com/c1cw1tD.gif

Ghost @kuharido I have an older brother. Two years older. He has pale skin, blue eyes, and dark brown hair. A lot are suprised we're brothers with the same parents. We get alongppretty well. We'd fist fight as boys to test our strength XD.

Thank you. I heard of both origins of the Valentine’s Day. The second origin of it you mentioned is more accepted by people, after all it is Valentine’s Day~ That name~ The first origin is more academic(I prefer this tbh), “fertility festival”, it reminds me of our own ancient fertility festival. That March 3rd (lunar calendar), 上巳日, spring is indeed a good season!!!Besides,3/3, there are also 5/20 and 7/7(lunar calendar).
