at first the alpha kind of takes advantage of the omega’s feelings and they have a *toxic* sex partners relationship. (like bj alex at first) but the alpha kind of falls in love with the omega (idk how it just kinda progressed that way but the alpha sure was a tsundere...)
but because the alpha forced himself upon the omega, causing him to be pregnant, the omega took revenge and ran away from the alpha and is currently seeking shelter at the possible 2nd male leads’ house.
im only guessing, but the plot may be as such: since the alpha is desperately searching for the omega (who marked him), its kind of evident that the alpha is in love with the omega lmao. and then the omega cant bear to abort the child he is pregnant with.
a few years later, they will occasionally meet again, and the omega will notice how much the alpha has changed (probably the butler telling him how the alpha kind of abstained after he left and became a heartbroken piece of shit) and rekindle their relationship after much pulling and tugging.
and also, when they meet again, the omega will probably be with their child. the alpha believes its his child but the omega denies it at first (typical)
