Thanks for the update. Frankly, I can understand most sides here but I have to agree on Ares's complete BS on the emperor can do no wrong thing. What are you teaching Kai?!
But again, to be frank
Ignoring his last stunt, Ares was just reminded of his trauma and was left daydreaming and was then forcefully brought back to reality and saw a stunning Alicia
Kai, if everyone remembers during the early chapters, does show even when they were kids, he does care for his sister (remember when Alicia was still in denial and jumped on an actual river to attempt and go back and Kai tried to stop her?), remember everyone, Kai eventually loses his mom, and is aware his sis is trying to distance herself from him since a young age. He ALWAYS had a (rightfully) gut feeling, Alicia might leave if the opportunity brought itself to her (that's why he had to pull of an act/minor threat to Alicia when he was called out to the palace. Why would he care for these strangers who suddenly barged into his life when his sister is right there and is brutally honest with him? These strangers he can sense to an extent, are using him or his title or even downright underestimate him)
As for Alicia, well... its self explanatory this chapter.
Dunno how Ares is gonna semi redeem himself with the fanbase/readers though. His gut feeling was right, Lancelot is a tough love rival when he even has history with her!
