A Cup Ablaze with the Years

A Very Humble Male Lead Who Loves the Female Lead Desperately and Begs Her Not to Leave, I Want Something Extremely Angsty

Looking for books like "Utterly Humble, I Only Want to Be Her Dog". The male lead stays even after she uses him and still acts meek and submissive toward her. I don’t want plots where he uses a child to manipulate the female lead.

Older Woman, Younger Man, Yandere, and Unhinged

Looking for a Slightly Angsty Novel Where the Female Lead Distances Herself from the Male Lead Whenever She's Angry

Something like Pu Tao and Shi Jingci.

A Hero With Obsessive Possessiveness Who Calls Her Baby and Gets Clingy, While the Heroine Stays

Looking for books similar to Reborn: The Abstinent CEO Knows How to Comfort, Flirt, and Act Cute (She Came from Heaven). The male lead is cold in front of outsiders but acts spoiled in front of the female lead. He becomes ill whenever she leaves and loves calling her “baby.”

A Devoted Loyalist Who Loves Only the Female Lead and Would Do Anything for Her

Looking for books like "The Good Girl Went Too Far Training Her Dog: Slap Him, Then Make Him Lick My Palm". Any stories where the male lead gets trained like a dog?
