UFD's manga / #brothel(2)

Oh, it wasn't even hot.. no sex scene... Only short story about brothel with zombies... Zombie was supposed to eat his customer, but he felt in love and showed him way to escape...

Dominate omega and alpha with trauma from past. When alpha was younger he attacked omega in the heat. He can't remember what had happened but he found the omega covered in semen so he probably raped the omega. Now alpha met one omega in a brothel... They fell in love and alpha confessed. And then omega said that he was the one who was attacked by the alpha.
