They nailed that in the drama - his bratty persona lol. Can't recall any other ML right now off the top of my head who was that bratty but not to the point of annoying.

Memory loss Su Yishui may be arrogant, but i think he had this care more for those who were near to him, or those who were actually nice to him. He might probably annoyed with RR bcos his past self(before memory) love her. Hhehehe he cant deny he still loves her.

I liked how even though he was a brat, he still remained consistent to his character. He reminded smart and could see through Dun Tian. And he could tell Ran Ran genuinely cared for him. As well as his students.
