Here's a question that popped into my mind today... after re reading this chapter.

Sumin's car was bought by Seju

Sumins house was bought by Seju

Sumins company was bought and is owned by Seju

Sumin is getting some inheritance by Seju's father

So... has Sumin accomplished anything by herself? As in, there something that Seju hasn't facilitated? It seems that in school, Seju was helping her study, getting her first car, sending her parents on a trip, driving her to school.. so what else has Seju done to make sure Sumin is happy but that we haven't seen..

I'm trying to determine the worth of this woman and I can't for the life of me find a reason to say "she's worked hard"
