He's not actually a cheater. The past princess ordered Robia to be with the other woman, i think? So it's not actually his fault.
whatt?! i thought he’s the one who initiated himself to cheat on FL with that trashy black hair maid Σ(っ°Д °;)っ
In chapter 6, the past princess asked Robia, in their first night together, "that was boring" "do you want to sleep with another girl in front of me?" Robia loves the Princess, even after all those hurtful words he said to him.
then i take back my words, the past princess is much worse than the shitty trashta, even tho she alr have heaven full of beautiful men （/TДT)/
kinda feel bad for the fcking cheater robia
