Li Moli, who was never valued by her family growing up, is forced to marry in her younger sister's place.
From the start, things take her completely by surprise, like opening a mystery box. When she meets the man she is engaged to, a ray of light shines into the dark, damp corner of her heart.
Momo is gentle-tempered, while Pei Che is a roguishly handsome bad boy. Though they seem to have nothing in common and their personalities don't match, they gradually fall for each other as they spend more time together after marriage.
Pei Che is a master at spotting fake sweethearts. He always keeps a safe distance from other women, making sure she feels completely secure.
Momo slowly develops feelings for Pei Che, but she's too timid to confess them.
As they grow closer, they both realize that they want more than their current polite, respectful relationship. Each is looking for a chance to express their feelings.
