Hwon and Jong Jin are foils of each other and it is even more evident in this chapter.
Jing Jin's way of manipulating Woojin is via appealing to his logic. This shows how Jong Jin is the more academic of the three. He's has a systemic thought process.

Meanwhile, Hwon and Woojin's interactions are intense and passionate. Their relationship is toxic but they stay together, because they follow their hearts rather than their brains.
