It's as the thunder crashes and she leaps into his arms that he feels the deep lance of desperate worry slash through him. It's as she curls her fists violently into his spine, hot tears smearing across his bare chest that he realises he loves her.
She's whimpering brokenly and it makes him wrap his arms around her. The terrified shakes are what makes him pull her flush against him, guiding her head carefully into the crook of his neck. She barely reaches, her breath panting across his clavicle as she buries her fingernails into his back. He doesn't want to acknowledge the sharp pang of desire and protectiveness, but it's curling through him, insinuating itself when he's least prepared to fight it.
It's to thunder shrieking through the sky that Kyouya finally gives in. Bringing a hand up to cover her ear he holds her breathlessly, carefully assimilating every curve of her body against his, the slow evening of her breath as she calms down now the thunder is muted.
She feels safe in his arms, safe enough to release some of the panic. The realisation warms Kyouya in a way he hasn't felt since a blonde aristocrat held out his hand, a kind smile upon his face.
And it's at moment that Tamaki throws open the door, anguish in his eyes.
It's at that moment Kyouya realises he has to let go.
Tamaki saved him. And now he loved this girl in Kyouya's arms. It didn't matter that Tamaki didn't know that yet.
Kyouya couldn't deny him his own saviour.
So with two loves warring and screaming inside him, he lets her go. Gives her to the blonde haired hero.
And as he watches her curl into Tamaki, he smiles and turns away.
