For people who want to know what happens:
Jin is a soon-to-be CEO and Namjoon IS a CEO. He hasn't revealed his name to the public cuz of privacy and is known as RM.
The two of them, then meet together for making Weverse, without knowing that they had already crossed each other's paths. How? Cuz of communication. Jin was taken from his mother due to her death which left a deep scar, he had no one to trust from then. But he trusts his mysterious phone caller Joonie. Which is obviously RM, Jin and RM don't get along well but Jin and Joonie do. Both oblivious to this of course. As time passes, Jin and RM do get along, but just as friends, until RM starts getting a crush on Jin, oblivious that Jin has a crush on his other side, Joonie.
It's like your there but you not there. Jin confesses to Joonie the same day RM was going to confess to Jin. Jin gets rejected by Joonie and he was HEARTBROKEN. RM sees this and confronts Jin. Then after explaining the situation both realize the truth. Then some chapters later they start dating, Fluff, smut, and whatever you want to imagine as the ending.
Oh and Jin and RM, basically Namjoon merge their companies. They resign as CEOs after a few years later (Just like Bang PD) and live their peaceful lives together. (P.S Jin being the love of his life, gets to know RM's name)
