(BL) Rejected by daughter's second male lead

It's been twenty years since I transmigrated into a child-rearing romance fantasy.After successfully pairing my lovely daughter, Cecilia, with the novel's original male lead, I, Gillen, vowed to live out my second life in peaceuntil an unexpected obstacle appeared before me."I honestly wasn't going to say this since you're Cecile's father, but""?""I have no feelings for you, Duke."That obstacle turned out to be none other than the second male lead, Yuan.Already well aware of Yuan's serious personality flaws, Gillen tried to remove this nuisance lingering around his daughter. But instead of sticking to the plan, he somehow ended up looking like a shameless man chasing someone twenty years younger.In the end, to settle the situation, he promised never to appear before Yuan again"Thank you for accepting my apology. Then I suppose this will be the last time we see each other. Farewell.""What? Last time? What do you mean by that?"For some reason, Yuan started seeking Gillen out more persistently than ever, eyes blazing.My daughter's second male lead why on earth are you doing this to me?
