I don't care that Garon and MC are endgame (though I'm not 100% positive that they are). I came into this story expecting it to be toxic. I have other cute and wholesome manhwa's that I'm reading anyway.
So nice to see that the sibling relationship transcends cultures and languages, and we've all suffered the same(/TДT)/ (coming from the youngest of three)
Can they communicate, please?! ヽ(`Д´)ノ
