[Childhood friends]

[In this story, elementary school lasts six years, upper elementary school three years, middle school three years, and high school two years, so all the protagonists are adults.]
When he was six, Lin Xiting's birthday wish came true: a boy moved in next door and called him "Big Brother."
Su Yanqing was two months younger than him, with skin as white as snow and eyes clear as glass. At a single glance, Lin Xiting decided: Heaven had sent him a little brother, and he wouldn't trade him for anyone.
From elementary school through high school, they were inseparable as the seasons turned. He was used to being the big brother, used to always having him by his side.
Until, after they grew up, Lin Xiting suddenly realized that the way the little one he'd protected for over a decade looked at him seemed different.
And his own heartbeat seemed... to have changed long ago, too.
