Of course they're dragging it out, there are very few BL out there where the characters come out to their parents, and Jaehyuk is trying with all his might to appear good enough to his family so they look past the shock and recognise that Garam made him change for the better, that takes time. In the meantime, of course there will be sex and other subplots, like the guy who handed him his business card, whom I'm 99% sure will scout him as a model.

He's just 40 if you have ED at 40 you NEED to go to the doctor why do Japanese people think you become an ancient relic as soon as you hit 35

ED is extremely common at ages 35+ and is not an inherent sign of a medical ailment ??? I get what you’re trying to say but its backwards to act as if ED is not a normal thing and is only reserved for people with something wrong with them or the so called “ancient relics”. having ED is completely okay and this manga did a good job normalizing it.
