UPDATE: According to the head translator Meru Meru Bom Bom, FLOWERS 2 is scheduled for a 2017 release in the West. The link to the FLOWERS 2 English page below has been updated with character bios. WARNING: Contains massive spoilers for FLOWERS 1.

Readers who have gone through the first title will know that the sequel takes place immediately after the events of one romance route in particular.

If all goes well, meaning that there are as few hiccups as possible with the translation and release date, all four FLOWERS games will have been localized by 2019 or 2020.
