I like how the first-year just casually shipped Yuzu and Harumin right in their faces.
I've been shipping Yuzu x Haru since Chapter 9 or whenever Matsuri went into "troublemaker mode". I thought all would be well after that very hot kiss between Mei and Yuzu in Chapter 8, but Mei just became even more undesirable to me in the chapters that followed. I suddenly woke up to the reality that nothing about her was worth crushing on aside from her pretty face. Harumin, on the other hand, has always been a reliable friend to Yuzu, and she does make some really cute faces like this one: http://dynasty-scans.com/chapters/citrus_ch09#20 Doesn't that just reek of genuine concern???
In all honesty, I believe that a Yuzu x Haru pairing is the healthier option for Yuzu's heart. It also wouldn't be difficult to understand how one liked the other if ever they do end up falling in love -- something that I find hard to see with Yuzu x Mei because even though time has already passed, I still can't feel that what they have is something deep.
