### Summary
Based solely on the provided source material, the current chapter continues the explicit hospital encounter between Seo Seunghyun and Lee Youngjin. Seunghyun enthusiastically performs oral sex on Youngjin, with the scene emphasizing their significant size difference, Seunghyun's smug eagerness ("eating the booty like groceries"), and Youngjin's blushing reactions. A notable and frequently commented-on moment involves Seunghyun licking his own semen, which readers found both shocking and unexpectedly sexy. The encounter includes oral and manual stimulation but deliberately avoids full penetration, consistent with reader speculation that Seunghyun suspects Youngjin's pregnancy despite no verbal confirmation yet. Physical details like Youngjin's changing nipples (darker and larger) and the aftermath involving an unusually large amount of semen are highlighted. The overall tone is intensely erotic and playful within the absurd hospital setting, focusing heavily on Seunghyun's desire and the physical act, while the plot point of Youngjin's pregnancy revelation remains pending.
