It's really hard to tell because the lady who slapped that kid and told him 'he should be grateful she's still keeping him alive' is dressed quite nice which aligns more with Seungeon's fancy background. Also, we already saw in former chapters that he is regularly brutalized and beaten by his family. His sister slapped him as if he was a dog last time and he looked like he is used to such behavior. So sad! That being said, we know nothing about Jiwook's past and his mother. He only mentions his father so there's a possibility it's him rather than Seungeon! I am so confused xD
Who's the woman who was slapping him in his flashback? Was it his sister? It doesn't really look like her. Could it be his step-mother or something?
