Please help me find this omegaverse

The mc is a poor omega and the ml is a chebol, the ml helps mc work as he tells his friend who's a beta to take him as a househelp, then once accidentally they sleep together, so the omega leaves his job as the house help and the male lead cuts contact with him, but then later the omega realises that he's pregnant and he goes to the ML's office to tell him and the ML accepts him(ml is a green flag).

I don't remember more than this
