I don’t think he thinks that gray hair wants his position, it’s that he knows if they get together the shareholders will revoke his position and give it to gray hair because now they’ll finally have an excuse to. In omegaverse society omegas are on the bottom and in the eyes of many they don’t deserve to be anywhere else. It probably bothers them so much that there’s an omega in his position so they’ve been waiting for him to get pregnant or married so they can pull the “weak omega” card and replace him with an alpha and “restore balance”. That’s why he refused to get married or have kids but now his father is sick and wants to have grandchildren so he’s being placed in a difficult position.
I honestly don’t think the gray hair guy is in a position to steal his position like he’s the chairman son. He’s marrying him and knocking him up which maternity leave might take him away from his position, but I don’t think marrying him would give him a right to MC’s position. I mean they could try, but I just don’t see how it would give him the right to the position. I mean it’s not like it’s a kingdom or something.
Ohh yea cause I coulda sworn he said something along those lines.and I think he definately has some sort of place in there cause how else would he have been able to go all the way thru the building to the MC office. Also I feel like he has to have some type of power cause if the first couple of chapters he had a spy or whoever figure out the conversation the MC had with his father in the hospital.

GIVE HIM A CHANCEEEEE!!! Oh my goshhhh and he would prolly make such a good father and husband…Ugh. Why? and then the MC has an entire misunderstanding thinking the gray haired ML only wants his position when really he wants to be a submissive hubby.
