13 parts Complete 《Younghoon × Chanhee》
In this world, you can find your soulmate at the age of seventeen or more. Less than that wont work.
Its simple, really.
You just need to place a white-coloured flower on your mirror. And the next thing you knew, the flower will be gone within 5 days.
Because the mirror everyone has in their home, is connected to their soulmates mirror.
And if the flower is gone, that means its been transferred to your soulmate's mirror.
Just wait for a week, and you'll have your flower back instantly. With the name of your soulmate with it.
But maybe for Younghoon, it is hard. Maybe, just maybe.
