Please Cry, Crown Prince - Chapter 35

I get that he lost his daughter, but treating fl like that just because she looked like her is kind’ve unfair in my opinion. I get how hard it is to move on from someone but I feel like the Duke is using her to cope with the fact of losing his other daughter. It feels like he is using her as a second chance to “protect” her as if the other daughter was still alive. I’m not sure if that made sense but that’s just I how percieved this chapter.
