Because of certain plot twists in the last episode the drama might get a lot of hate n yeah it was at some point unnecessary or atleast i wished taeyun had got some justice. Can't see seonu n his mother in power tbh.
Overall the drama was great it was based on revenge which was rightly taken ig. Cuz at certain point the person holding grudges seeking for revenge gets tired at certain point. That's what Seo deongu's character portrayed i feel. You let the person suffer one's and it satisfies you at a certain point, but when you r not someone who do wrong to others it still haunts you cause you were never the evil person.
They could have sumed up S2 in 8eps if it was happening. But i think we r not getting it.
