Fudge. Why would anyone think mr. Ha is the tops younger brother? (Although i agree that they have same face structures and hair) but please don't go down as low as thinking they are related. Not now. What if mr. Ha is someone mr. Gu's brother knew? What if they are acquaintance and his brother ask help from the bottom?
Tbh, i am nearly dropping this because of the plot but when i found out that our mc is not the bottom, i cried for joy. And second, the artwork is soooooo damnnn blessed
