Hopefully Taiyaki can put the complete edition (rather than just the SFW-ish one) out in English somewhere after the Fanbox period, I can't imagine how it'd feel to read "Distant Farewell" without Tamamusi's goofy emotional counterweight afterward.
Yuri Hub have reportedly found some third party platforms to sell it on. They're just waiting for approval before they announce anything.
It does suck because the go-to platform for their releases, Pixiv's own Booth, would regard the content of this anthology as Adult, regardless of how softcore it actually is. Since Paypal can't be used to purchase adult goods and international credit/debit cards don't seem to work on Booth atm, it makes it harder to release to the people who'd actually want to read it in English, hence the planned Day and Night releases.
