Can some kind person please jog my memory on the ex-girlfriend?

I don’t think she has appeared yet

So for once it’s not my terrible memory. Thank you!

haha I think she will come out soon to make MC jealous

I can’t imagine the Duke showing any emotions to anyone. Seems he’s just learning now. I can’t wait to see this person. Also, I think our MC needs a little push right now. Looking forward to the drama!!
