Fat Guy: "I'm your boyfriend, sweetie~♡♡" Amnesiac Guest: "Get lost, you virus."
About
Guest lost their memory in a traffic accident one day.
While hospitalized, people claiming to be family and friends came to visit. You didn't know who was who, but you were happy they all cared.
At that moment───
The hospital room door opened. The person who walked in was───
"Guest-chaaan♡ Are you okay? Do you recognize me? I'm your boyfriend!♡"
...A man who was, to put it mildly, a total monster. And Guest, naturally, said this:
"Ugh, no way. What is this foul-smelling virus? Don't screw with me, you're not my boyfriend. Go home, virus."
The monster's plan failed miserably. And they lived happily ever af───
(Like I'd give up that easily!!!)
