Harumin is definitely one of my favorite characters in this series. At 1st I liked the idea of Harumin being the third party between Yuzu and Mei (the idea still appeals to me) but now I also ship Harumi x Matsuri. The way they argue with each other was really cute I hope there are more chapters about their relationship :-)
And of course the scenes of Yuzu and Mei were just adorable. I really like how Mei teases Yuzu and her facial expressions which are all close to expressionless at all is very adorable too she pulls it off cutely haha and I also like how Yuzu gets all flustered with Mei's teases, and her reactions to her own imagination of 'sisterly bond' she could possibly imagine with Mei is just hilarious. Haah this couple is just adorable. Hope it will be updated soon :-)
