Yes! It’s not just my favorite yuri but it’s my favorite series of anything all-time haha. If you like emotionally moving stories with realistic characters, you should love Flowers. It’s one of those stories that I thought about almost every day for months after finishing it because of how good it is.
Some other ones that I enjoyed:
Aoishiro | vndb - This one is a action mystery game that is far more plot focused. While the girls are yuri, romance isn’t a focus in the game at all but the story was interesting.
Tsuyuchiru Letter ~Umi to Shiori ni Amaoto o~ | vndb - This is a cute story with a bit of a unique premise to get their relationship going. Mikoto is blackmailed into dating Shiori and thinks it is Shiori who blackmailed her, but Shiori actually isn’t aware of it at all so when Mikoto comes to her all pissed off asking to date her, she’s confused but thinks of it as an opportunity for something new happen in her life. Despite the “blackmail” premise, it is a more light-story but I thought the way they developed their relationship in it after starting off that way was really good.
Lilycle Rainbow Stage!!! | vndb - If you prefer more slice of life cute stuff, this is a good rec. There’s no real plot but there are like 8 different couples and you can read through their relationships however you want (so can skip couples you don’t like). It’s nothing ground breaking but I thought it was a relaxing read, cute art and good comedy.
