Was kinda hesitant to read it since looks similar plot as Strawberry Mashmallow, but did it anyway since got a free time.
It's kinda bad that everyone's bithdays are basically the main plot of the story and they even repeat it every year. I like the dynamics of the sisters more than the others. It's so heartwarming, even compared to relationship with Hana which is only grow based of bait foods which is also repetitive.
