As much as I agree with you on the appeal of breaking out of "rich boy, poor girl" cliche, this one is not it. Kwon is rich, he just is living incognito now. In the second half, after the time skip, you will see that. If you want real "poor boy, poor girl", read 1136.

How do you know the plot already? Is this based on a light novel?
Yes, it is from a web novel with the same name
To start off, it's actually nice that both of them are on the same level of social status. Not the typical rich RICH boy bagging a poor girl trope. They both have family complex which they establish emotional bond over. They understand the struggles of each other and are slowly being transparent about it with each other. It's super nice to see and read stories where the couples are on the same emotional wavelength where they can care for their partner. THIS IS A 10/10 FOR ME
