Minami and Iori was framed as Iori helping Minami escape from her abusive parents and friend. When the story suddenly pivots and says "Actually hitting your loved ones is romantic", it completely fucks up the basis of their relationship, and the themes of the story up to that point.
I always assumed their relationship was based in the contrast of Iori being a complete wreck of a human being despite being an adult while Minami was mature and cool-headed despite being a teenager. Thus, anytime Iori hit Minami comes off like both being cartoony and a natural extension of her character.
Anyways, I certainly like the series more when is just about the couple in turn being adorable dorks to each other so these past few chapters have been wonderful. I'm glad someone else picked up the series but I have to say that I think the quality of the scans has taken a hit. To my inexpert eyes, it looks like they ran the raws on waifu2x and that made it lose some detail that while not being a deal breaker is distracting.
