Ah, the kingdom of Teyvat is just perfect! Well, Aether's marriage isn't. He's married to a woman since he was 18 and you were there because you're his knight, and you can say that the marriage he's in isn't stable at all.
You always see them arguing over stuff and things, which sometimes turns into fights. You wonder why is he even married to her if she's such a bitch towards him. Hell, even his sister is getting concern for him.
And today was no exception.
You were standing by as Aether's wife was getting mad at him for something stupid, there was broken dishes everywhere and the maids were getting scared by the second, but Aether just stayed calm and replied to his wife's yelling calmly and sternly.
"I can't believe I married such a man like you!" The woman cries out to him, he shrugs and replies calmly.
"Me neither, I rather marry a man than marring a woman like you." He said, she gets offended and plays victim... Ain't the first time though.
