Mei asking Sara if she needed her is a question she should have asked Yuzu, the answer would have been obvious.
Oh my god YES that would have been so perfect!
"Do you need me Yuzu? - "Of course I do, more than anything" BOOM! happy ending :D
I bet the author thought about it and then was like, nah let's not.
The amount of long, drawn-out drama in this series is too damn high (╯°□°）╯︵ ┻━┻
I'm not so sure that this is actually going to be a love triangle I think Matsuri just wants to tease Yuzu and have some fun and is trying to make Mei jealous (because it seems fun) sooo I'm actually kind of happy with this development since I feel that maybe Mei will finally realize and accept her own feelings and stop pushing Yuzu away. Ah, I can't wait to see her reaction ^_^
