Not all of them. Meru and Kaere have this pretty stable romance/rivalty thing going on and lately things have been pretty heated up. The only real problemo is that while Kaere has feelings only for Meru-chan Kaede is still somewhat attached to sensei. These thing tend to get kind of complicate on long term but I'm absolutely positive that they'd work it out if they just would open up a little. Rome wasn't build in one day either, you know. Baby steps.
