Before Zhao Ye left home, he was still convinced that Song Song'an was his most beloved little sister and that he was an excellent older brother, just a little overprotective.
Then, one day, he suddenly figured it out.
Afterward, Zhao Ye felt that his entire being could be summed up in two words: an idiot and a beast.
He slapped himself twice, then happily accepted it.
A gentle, unexpectedly different heroine X a clever, proud male lead
Two-year age gap
Content warnings: The heroine calls the male lead “big brother.” Childhood sweethearts, told in a slice-of-life style. Set in the early 2000s, not a conventional modern romance, and without melodramatic plot twists. It should count as a sweet romance, more or less, about seventy percent sweet and thirty percent bittersweet.
