Our Pheromones Say We're a Perfect Match

My next book is He Thinks I Came from a Psychiatric Hospital. Thanks for adding it to your reading list.

A heads-up before you read: The protagonist who gets pursued used to sleep around and live recklessly. Both leads have a messy romantic past. Please don't click if you can't accept that.

A cultured scoundrel of a pursuer, Jiang Ge x a sanctimonious pursued lead, Xie Yang

Xie Yang prided himself on being detached from love. He'd passed through countless flower gardens without letting a single petal cling to him.

Then one day, he met someone just like himself. Xie Yang found everything about him appealing, except that their pheromones were incompatible.

Three months later:

Xie Yang: No one is more suited to each other than we are.

Theme: A prodigal who turns over a new leaf is worth more than gold.
