(오래된 약속 - "Our Old Promise")
When 18-year-old Shen Wenlang, an S-Class Alpha known for his brilliance and arrogance, wakes up one morning to find himself 19 years in the future, nothing makes sense.
He's now 37 years old, married to his childhood best friend Hua Yong, the Orchid-scented Enigma who has always loved him quietly-and together, they have twin sons, Hua Shen and Hua Lang, both high school Alphas with a faint blend of orchid and iris scent, inherited from their parents.
But something is wrong.
In this future, Wenlang is on the verge of divorcing Hua Yong. The house is quiet. His sons avoid him. Hua Yong doesn't even look at him with affection anymore-only resignation and pain. And everyone keeps whispering about "Gao Tu," the Alpha, Wenlang supposedly cheated with.
Will love be enough to mend what time-and betrayal-has destroyed?
Or will the younger Wenlang discover that saving his marriage means confronting not just the future, but the ghost of himself who ruined everything?
Shen Wenlang and Gao tu were close friends in highschool but for a misunderstanding they separated from each other.. 8 years later they again meet but this time as a boss and secretary..
Shen Wenlang's parents forcefully marry them and tie them together in a bond..
What will happens after that?? Did the marriage makes them closer? Or they again apart from each other???
