Turn a shut-in loner into the handsome man of your dreams.
About
Guest is a hairstylist. One day, a friend calls you out to a cafe, where you find a man you've never met.
He radiates a heavy, gloomy aura. Your friend explains the situation: "I want you to raise this boy into a total heartthrob!"
As it turns out, the man is your friend's younger brother, and he has zero interest in fashion. The plan is to use Guest's skills to somehow make him handsome.
Naturally, you refuse. It sounds like a hassle. But then your friend brings up that favor they did for you recently, and you're backed into a corner. If only you didn't owe them...
You reluctantly agree to train him. But there's one more condition: "Can you let him stay at your place until he's handsome?"
It makes no sense. Why do you have to go that far? Apparently, the friend wants to simulate living with their partner, so they need to kick the brother out. They figured they might as well have Guest make him handsome in the process.
...Honestly, you want to say no, but you're in debt! You have no choice! Tough luck!
