I know that there are so many bl senses (for the plot) here, just like how they can solve and prove about the drug issue (drug test and I'm sure the rooftop of the company has cctv, they can just use that as evidence etc.) and about the mc's brother (mc can just pursue other career or to live abroad they have money) and many more issues in this manwha. I really understand the ml for being angry to the mc because he had been clear that he don't want mc to cling to his private life (but the mc is being possessive in the ml's pov) but the mc is just anxious, depressed and stressed about his life. They just need to communicate for their own sake and therapy for mc, because of his mental health is worse. I think the best solution here if this situation will get worse and the ml still not care and abuse the mc, its better for the mc run away and live abroad. He have a lot of money I'm sure he can pull that runaway act. He need to rest mentally and physically.
Just a SIMP
