I really really liked the common route. It had great progression of the sweets store, likable characters, solid humor, decent character development and some really nice wholesome emotional moments. Only things that bugged me were a few jokes, mostly related to Shizuka and occasionally JC. Just based on common route alone, I'd give the VN a 9, maybe even a 10.

Now the character routes are more hit or miss. All of them have some really nice moments but also some really annoying or stupid moments that bring down my overall enjoyment. These don't even related to H-scenes, where the heroines randomly become succubi.

I don't like how all 4 routes have the romance start due to some really stupid misunderstanding.
Sasa has the thing with Ryo's apparently having ED, Raiha has the whole miscommunication with the friends with benefits thing, Ushio having Ryo apparently using shoujo manga confessions during non-romantic situations, and Kanon having supposed 'pretend dating'.

All of them except Raiha mostly resolved themselves quickly, and when the actual romance starts it is pretty nice. I just wish they all didn't start like that.

The other issue I have is... the two routes with actual drama, Kanon and Raiha... are terribly executed. Raiha's is just thrown in at the end and resolved relatively quickly. Kanon's drama has this really weird over the top solution and once again is resolved quickly. Both felt terribly executed compared to the more down to earth drama in the common route which I thought were more real issues and the development for those felt a bit more realistic while still resolving relatively quickly.

While Sasa and Ushio routes ended up having much less drama and shorter, it honestly made them better for me just cuz they got to the point with nice wholesome conclusions. Ushio's in particular was nice for Ryo.

Now would I say the routes are bad? Not really. Overall they end up being meh-to decent at worst, but compared to how good common was, I was disappointed.

That said, all 4 of them do still have some of the wholesome moments. The endings of Ushio, Kanon, and Sasa routes were all quite nice. Raiha route... at least she was better than other friends with benefits routes where she's quite a bit more honest which leads to some nice scenes occasionally.

This puts me in a bit of a pickle of how to rate it, maybe a high 8 or a low 9?

I still overall enjoyed myself most of the way through, the consistently wholesome/comfy nature is pretty much what I've been looking for in a visual novel for a long time. I'm just really disappointed in certain aspects of each heroine route, unfortunate.
