(You're Soap.)

Soap had been injured on a mission and Ghost was taking care of him, helping him do certain things that he could do himself. Stuff like showering or eating. Soap didn't mind it however as he and Ghost were in a secret relationship. Today was no different.

Soap was stood in front of Ghost who poured a little medicine into his mouth, but then shocked him by leaning down to kiss him before his mouth has even closed.
