@Ariria You mean Lancelot? I think it's just based on the translation. She likely calls him "Oppa" which is how a younger female addresses a slightly older male in a friendly manner. It also means "Older/Big Brother". Calling someone that doesn't necessarily mean they're related. (We Asians love to treat people like family if we're close enough). It can be a bit confusing but I find it's better given the setting of the story, rather than leave it untranslated.
I keep re-reading this coz it's funny seeing Ares get worked up after ignoring her when she's all glammed up.
HAHA Ares is shaken up, he was trying hard to keep away Lancelot from Alicia and now they actually have this backstory. But I feel sad when Alicia misunderstood Ares' reaction of her dressing up, he was so occupied with his thinking.
I think at least 65% of the reason why I love Lancelot so much is because of how jealous he makes Ares xD Don't get me wrong, he's for sure the Best Boi, but I think I'mma keep my Ares/Alica ship <3
Thank you for your translations and all the work you put in, but y'all, I CANNOT WAIT for chapter 62?!
