I don't know why but I kind of feel sorry for Youngchan, even though he stood up to his dad, since his dad was about to abuse his sister again. But The sister became afraid of him as well, and sometimes Seo is afraid of him also. He was just protecting his sister by the looks of it... When Youngchan saw that Seo was afraid of him he immediately became a scared pupper.
Who the F translated this? I really appreciate you for that but atleast put a little bit more effort than that. I totally get the "you paid for it" but also YOU technically volunteer to translate it to everyone. I saw someone commented that they would totally help you proofread it or support for it. But ATLEAST make it sensible to actually read and still understand the plot.
They gonna snitch for sure unless... An offering is made
