Hate mc tho, idc that he’s isekai’d, he is in another world so there are obviously other rules, feels really bad for sister, she did nothing wrong from the beginning she always was respecting and helping him, that selfish cunt MC running away like that, for real. Imagine for 14-15 years you know that u will marry someone and u love him, but he f*cking runaway because he is selfish piece of sh*t. At least he should try more to solve this problem, maybe next one try run away by killing ur self so you won’t have to face any problems stupid MC
