"Our birthday."
Dongwoo immediately opened the door and looked at them. Then, he saw in Seojun's arms, a big chocolate cake with a lot of strawberries on top.
"Since when does chocolate go with strawberries?" He asked, out of the blue, but that was definitely the wrong thing to say at that point, so he cleared his throat and turned serious again. "Ahem."
He looked them in the eye. They were sincerely apologetic but he couldn't get it.
"You knew today was your birthday," Dongwoo said and they nodded. "Then why did you scare me?"
"Because you forgot." They both ended up chorusing.
"And what makes you think I did?" He asked but then realized he didn't exactly wish them a happy birthday before they left.
Well, that was because they made him unable to wake up and see them off before they left for work, and even if he did see them, he wouldn't have wished them either because of the surprise he was preparing.
