Just finished it in one go this is soo cute really. The background blend perfectly with the characters design. That's an impressiveee job
One thing tho I'd say that the protagonist's answers seems too flat most of the times. That'll be great if they was some sort of inside jokes between the charac to choose or something like that.
Looking forward the kiss scene~ (I already imagine them in a sort of Japanese festival date with some fireworks bg and everything lol)
