My 39th Book, by Xiao Jiujiu

Devoted couple + exclusively doted on + emotionally supportive lover + age gap

(A clingy little rice cake baby, a sun-bright red fruit, a lover she’s instinctively drawn to)

Sang Yan first met Ruguo when she was still in high school. She was young, but he fell in love with her at first sight. He thought he’d confess once she was an adult and make her his. But the year Ruguo came of age and started college, she got a boyfriend, so he had no choice but to bury his feelings.

He never expected the little fruit to get her heart broken so soon. His hopes came alive again. Little Guoguo, this time I won’t let you go.
