My name is Wu Gan. The spring, summer, autumn, and winter of that year are something I'll never forget, because that's when I met Huangfu Yueyue. We went from strangers to friends, from having crushes to falling in love, and then, as the awkward sensitivity of adolescence tugged us apart, distance grew between us. I never regretted meeting her. The feelings we tucked into notes and the walks we took side by side after evening study were the brightest lights of my youth. I only regret that I wasn't good enough back then, and couldn't become mature enough to keep the girl who filled my heart with joy.
