He loved leaning close, feeling broad shoulders against his softer ones and against his back as he read, tried to decipher English under a helpful hand.
Aiichiro loved hearing that sweet Australian accent when Rin leans in and whispers English no louder than a breath.
He loves hearing that accent pronounce words in a way that he could never succeed in doing himself, loves knowing that every whisper is just for him, and loves hearing whisper soft Japanese as perfect as the English when Rin switches to translating for him, making it look so easy.
Ai smiles as he treasures the soft sound and hopes that one day he'll read it better for Rin's sake and somehow manages to fall more in love with him every second spent by his side, learning to understand English.
He leans closer, silently asking about what is probably the verb of the sentence as Rin leans closer and explains so very easily what it means; he wonders if he'll be able to write in English for Rin, a simple sounding declaration of love.
Aiichiro smiles, leaning closer and whispers his thank you and means it from all the way down to the bottom of his toes.
"I love you." Is as soft as a sigh on his tongue as he leans against Rin as close as possible, feeling the warmth spread throughout his being, taking any cold away with it.
"I love you too." Rin whispers back, first in Japanese before switching to that enchanting accented English.
Ai smiles wider, looking like an excited child on his birthday as he leans back to kiss Rin's cheek and spread the love delicately across every inch of skin he can reach from Rin's arms.
Rin blushes faintly much more beautifully than the girls on the romantic comedies that they secretly watch together when no one's around; Ai nearly giggles at the cute shading of Rin's cheeks as he leans even closer, feeling skin beneath his lips that was so beautifully trained for swimming.
Ai beams when he feels the first returning kiss that feels brighter than the sunrise and dances along his skin like the stars dot the sky.
He relaxes, lets Rin treasure him like he's made of the sweetest chocolate.
Ai only smiles wider in encouragement, "I love you so much, Rin." He can't help the fact that he nearly cooed the whole phrase as he relaxes further in his arms.
The mutters against his skin remind him of how loved he really is as he leans closer against him and wonders what exactly begins to be whispered against his skin.
Were they sweet endearments in English or barely spoken Japanese declarations of love that were too soft for Ai to understand?
He smiled contently and leaned back against Rin, placing delicate kisses along Rin's skin wherever he was pressed closer to Ai's lips in this moment.
Ai beamed and gently kissed Rin's lips, treasuring the shift of their kiss into the sweetest pull against each other.
