Helping Yue and Hyra land safely and seeing how much they were focused on each other made Chen's own heart flutter. They were each other's whole world for a little while and that was something special. And that gave her time to turn away from them and let them have their moment in the duck pond while she turns to Rose. 

And then there are kisses, Rose from the River! Chen's breathless and excited, her cheeks flushed red from the cold and the wind as she comes and throws herself upon you, raining kisses first on your cheek, and then along your ear (so flowery!) and down your neck before she works her way back up and around to firmly press those lips to yours. In fact, she might bowl you over entirely when she presses herself up and into you and takes a nibble of your lower lip while she's there. 

When the two finally part, still breathless in a new way, Chen's concern is evident on her face. Yes, even though she saw you step as though the air was as firm as a mountain, still she's got a cross little look on her face. "Why'd you wait until the last second, huh?" she asks you, Rose. You can see on her face that even though she'd made a tactical move in the air, even though she'd entirely correctly left you to her own devices, she'd actually been worried. What if she had been wrong? What if you'd been distracted or weakened or Cyanis had done something unexpected in the fall and she'd been wrong? So she's hiding it with an in your face accusation. But considering the height difference, doesn't she look like a petulant little toddler that you just want to snap up for hugs and tickles, hm? And doesn't it make you blush, too, knowing that someone cared for you, that your little girlfriend was really honestly worried and wanted to protect [i]you[/i] as though you were still a dainty handmaiden who might trip all over herself?

Indeed, Chen is so up in Rose's face that the suddenness of it bowls her onto her back and results in a "don't try and dodge the question!" as Chen comes toppling down on top of her, Cyanis entirely forgotten (and surely too busy trying to wriggle her way out of her new net and scoop up the rain of gold coins all at the same time). And it would all be too much if Chen didn't start laughing upon finding herself directly on top of her girlfriend and coyly bringing her face right up to Rose's face with a smile that requires almost crossing your eyes to look at her in focus. "I'm waiting, are you going to explain yourself?" she says, only just sticking her tongue out at her girlfriend.
