So from the plot, hyung gets babied up, hot dilf will ofc not want his alpha son to know he's already a baby daddy, so omega hyung will probably run away and hide the baby for yearrrs. Baby daddy already has a wife / husband purely for business (but ofc the legal one is in love with him). For the plot, he sees omega hyung, finds out he's still obsessed with him but he resents him, then he treats him like a total shyt by letting him suffer for how many chapters until they start fucking and figuring things out.
