Who died in this third part? It mentioned he was going to a funeral and it kind of made me think that either it was his sister that had died, or it was Satsuki. Either of them dying would have made the story bittersweet, but now it was just glossed over. A bit of a wasted opportunity if you ask me.
@Ilyia: He is texting with his sister about 法事 the events after the funeral in Buddhist, not the funeral itself, if she died how the F he can text with her? They mention about their father would come back the next day so this can be about their mother anniversary or their grand parents or whoever else in the family tree.
法事 7 times every 7 days from dead day. the 100th day from dead day. 1st year anniversary. 3th year anniversary. After 3th anniversary the widow or the children of the deceased can remarriage or marriage. after that every anniversary for each year.
by the looks of what they do in p.41. this is just one of those every year anniversary event.
This even is not the funeral, so this kind of thing is hard to translate.
