Letter number 4 here. Note: when I wrote the first letter, I'd never planned to make this beyond a one-shot so it says he comes by her grave every year. Well, let's just say it really hasn't been that many. Two, in fact, since Momo died. Thanks to: metsfan and Toshirolovr94.
Fact: March 20th is the first day of spring thus meaning that the New Years chapter was the start of a chronological order. It won't be random holidays and events all over the year now.
Dear Momo,
It's the first day of spring, the second spring since you've left us. Amazing, isn't it? Two years already seems like a millennia. Abarai somehow managed to get his hands on a peach tree and we transferred it to your grave today. It's not much more than a sapling right now but tiny flowers still drift from its branches. In a few years time, it'll be big enough to shade your grave and cover it in petals. I'd think that you'd like that. You did always love the peach trees in Granny's garden when we still lived in the Rukongai. I wonder what happened to those. I haven't been back in so long, though Granny sends word sometimes. I wonder if they're still blooming. Even though we've grown older and life's grown more painful, maybe they haven't changed.
