Story and premise

To save the orphanage founded by his grandfather and to pay off his debt, Somsak, who has been thus far financially supporting this institution with profits from his now-unmarketable adventure novels, decides to venture into writing a genre that the current generation is more interested in—"boys love" Seeing his grandfather's plight, Save—Somsak's Gen Z grandson—decides to land him a helping hand in this mission, although they often clash heads because of the generational gap. To give his grandpa real insight for his novel, Save chooses to date his friend who has confessed his feelings for him.
