### Summary
Following a public display of their protective partnership, the fragile stability between Lee Soohyun and Jung Eunsung shatters in a raw and emotionally charged confrontation. For the first time, they lay their feelings bare, exposing a fundamental schism in their perceptions of one another. Eunsung, burdened by trauma and feeling broken, attempts to push Soohyun away for his own good, even suggesting they break up. However, Soohyun, still trapped by his decade-long inferiority complex and obsession, refuses to see Eunsung as damaged. He continues to view Eunsung through the idealized lens of their high school rivalry, seeing only the brilliant figure he is determined to defeat. This disconnect is visually symbolized when, from Soohyun's perspective, Eunsung's clothes momentarily revert to his old school uniform, revealing Soohyun's inability to see the man Eunsung has become. Soohyun interprets Eunsung's vulnerability and self-pity as an insult, failing to grasp the depth of his trauma. The argument escalates to a tense cliffhanger, with Eunsung trying to shut Soohyun out of his home, only to be met with Soohyun's enraged and desperate demand to "Open the door," leaving their toxic, codependent relationship at a volatile breaking point.
