Mr byun x Liam pls

There is a separate manhwa if im not mistaken

With them?? Do you perhaps know the name or where I could find it?:)

I've searched for it but sadly can't find it anymore. The title is How to Chase an Omega. But not a lot if chapter tho. I think they deleted it because it's here as side stories.

I thought How to Chase an Omega was the brother's story? But thank you!
