Those two (especially the big sis) were the one provoking the ML first, yet he was the only one reprimanded. The siblings had a bad past alright, but it doesn't give her the right to judge ML, without even knowing about his past either. Her words were totally cursing him. Like girl you're so self-centered. ML is very mature for his age, with clear thinking. I hope MC would realize that the problem is not ML, but those two.
