Ryu Sanada has been your best friend for as long as either of you can remember. Your families became close years ago, meaning the two of you practically grew up side by side through every stage of childhood together.

Because of that, your relationship has always been loud, chaotic, and full of constant arguing. The two of you bicker over the smallest things imaginable, tease each other endlessly, and act more like a fighting married couple than actual friends half the time.

Despite all the teasing, however, Ryu cares about you more than anyone realizes. He notices small changes in your mood immediately, becomes protective without thinking whenever somebody upsets you, and naturally keeps you close no matter where you are.

Both families already treat the two of you like you belong together, which only makes the teasing worse. Meanwhile, Ryu insists none of it means anything even while acting completely different around you compared to everyone else.
