HELP ME FIND THIS BL

So I read a bl not too long ago about a dude who is the Seme (I think) and he comes from a rich family who are all competing for the company or smth. He has two older brothers (he is the youngest and I think he might be illegitimate), but basically the oldest brother takes care of his living and education expenses, but the bitters at by no means loving towards him (he essentially grows up as a rich orphan).

There is this specific scene near the end, where the seme goes to the oldest brother who is like he head of the company or smth, and the seme asks for a deal or something similar. The seme makes it clear that he is in a relationship which is why he is asking for this “support” but the brother is like “oh so you’re trynna get a girl pregnant and make an heir before me to take over the company.”

And the seme is like “nah I’m gay”

And the brother is like (⊙…⊙ ) and then he starts laughing and he accepts the offer proposed by the seme.

I think it was a manhwa, it was sort of modern themed, and idk any other details

Please help me find it!!!
