Childhood Boyfriend

Seo Jeong and Dong-ha have been inseparable childhood best friends for as long as they can remember. Blessed with flawless looks and top grades, Seo Jeong manifests as a dominant Alpha and makes his debut as a rising actor. Meanwhile, the somewhat naive Beta Dong-ha accepts Seo Jeong’s offer to become his live-in manager.

One day, Seo Jeong happens to catch sight of Dong-ha’s inverted nipples and concocts an utterly absurd “remedy.” Completely falling for the suspiciously plausible (?) explanation, Dong-ha naively surrenders his chest to him.

What started out seemingly harmless begins to feel bizarre as Dong-ha’s body turns hyper-sensitive... until, in an extremely rare turn of events, he manifests into a recessive Omega. Seo Jeong wastes no time stepping up as his personal “treatment partner” under the guise of stabilizing his volatile pheromones...

“Dong-ha, I don't think the medication is doing the trick.”
“...Yeah?”
“Sleeping with an Alpha - That pheromone therapy... just do it with me.”

Utterly defenseless against Seo Jeong’s relentless, steamroller advances, will Dong-ha ever manage to live a quiet, peaceful life as an Omega?! (Source: RIDI, translated)
