Intro

A short while after summer break began, my older brother also started his vacation and returned from the dorms. The hand that ruffled my hair was warm, and his narrowed eyes held a gentle heat. I love my brother's kind hands. I saw Arthur drop his gaze to my lips and swallow hard, but I didn't understand what that look meant.
