Comment by MommyDearest on Lia

@Lia The author of the manhwa had one before, I'm pretty sure, called "If You Hate Me So." Dojin and Hyesung are originally from there but as side characters. That story wasn't an omegaverse and was a whole different thing, still BL though. The author didn't want to waste Dojin and Hyesung, so they made a new manhwa with a whole different story and as an omegaverse with our MCs. In this chapter, what happened was Hyesung from this manhwa got switched with the Hyesung from If You Hate Me So. That's why he couldn't smell the pheromones on Dojin, and the ages seemed off. At the end we see the Hyesung from If You Hate Me, so questioning the Dojin from there and they are the Hyesung and Dojin from here.
