Nope. They are from the manga "If you hate me"
If you hate me so*
ummm Heesoo wasn't the one who got pregnant, it's Hyesung (￣∇￣")
Yhh I meant hye-sung
Reallybut they lowkey look like them
This is an original story about two side characters (Hyesung and Dojin) from "If you hate me so/If you love me so", and it's not an Omegaverse. I guess the author wanted to do a little cameo from the original story, and I found it really cute.
It really is!
Everyone needs to go back to chapter 20you need to!!! Its the chapter where heeso finds out he's pregnant but when they left the doctor's office he fell on the floor and started a tantrum and there was a couple and the omega was pregnant and they had another baby but the COUPLE IS LITERALLY THEM BUT SWITCHEDI thought I was going crazy!
