Nop. He was never intimate with Rose. Everything was an experiment. The reason he didn’t plant the baby in the MC is because he didn’t know if it was going to work or not. He loved MC in both lifetimes so much he didn’t want to put her life in danger. When she commit suicide because of rose insinuations he immediately ask for rose to be killed and went back in time because the whole rebellion and all was for MC…this because MC was going to be sent to marry in another country and he couldn’t handle such thing. Hope this helps!
But in chapter 85 it shows that Mikaeil was intimate with the 8th princess but he did it as a means to use her and he actually felt revolted by it too but in the previous life he was cold blooded and manipulative but in his 2nd life he's different. But Homunculi are not able to reproduce but homunculi are expected to provide "training" at night in that aspect...

Y'all, I'm new at reading this and I just want spoilers. Did ml really kiss rose?? In chapter 5? And did they make a baby fr?? I'm disgusted if they did have an intimate moment
