He runs away to get away from his family.
So does he run away again or are you just talking about the beginning?!
He only left once. After he finds out that his parents wanted to force him to marry his sister, he sets out on a journey until his sister marries someone else. Only, it turns out that she's a yandere who is obsessed with her brother and she's leading a group to look for him.
Oh yes I know about that. I was just saying what I said because when he sees her again I was hoping it wasn’t one of those stories that just give in, in the end lol.
I hope he sticks to his convictions and doesn’t end up with his sister!!!!!
