This is a fun slice-of-life segment. I despite the lack of tension, I do like these type of episode, it makes the characters more alive as they have other things outside of Karuta, which is nice. But this episode is leaning more to hilarious to be honest, from the valentine disaster and then that hook at the end (Which I don't know if it's a gag or not). I do hope they went through with that ending tho!
