Ha?? What do you mean?? They clearly explained in the chapters that they can't tell him everything especially when they started to know that Chayoung only remembers his memories when he was 28 yrs. Old. Gyuha can only talk about the things that happened in that time and it's true they are fuckbuddies that time. They didn't even confess to each other that time. That time is the most vulnerable side of Gyuha that he didn't want to encounter again. Chayoung didn't even believe that Gyuha is an omega. To be honest, Gyuha is mentally strong cause even though he knows that the Chayoung that's infront of him is the part of him he hates the most, especially if you recall the past. He still takes care of him, he even agrees to have sex with him also he indulges Chayoung's needs.
They only told Chayoung piece by piece when he was discharged and at home. Didn't you even notice, they didn't even show the kids to him when he was in the hospital. They only showed the picture of the kids thru phone. Did you see the look on Chayoung's face when it was revealed? He can't even grasp anything.
Gosh
Gyuha indifference really piss me off
I don't doubt that he loves Chayoung but holy shit the way he made they sound like they are fbuddy and their marrige happened without love for no reason
Bruh even tsunderes act like they love their partner
