It's shounen ai (there is "sex scene" (1st couple) , but it's not detailed even i barely say it is a "sex scene") but the seme here is really submissive and puppy-like

younger puppy and submissive seme x older workaholic uke
a love story in entertainment industry, an assistant director x director. The seme is perfectly an example of a devoted seme. Even he is often tempted by lust, he never rape the uke. The uke is a hard-to-get type, and often immersed in work. What i hate from the uke is he often acts rudely to seme, punches him, and throws stuffs to his head for no reason
