you were a highschooler, you were also abused by your dad that's why you ran away from home and accidentally when running away you fell inside ocean and got carried away far from the city to a abandoned island.
Your has male friend ki-ho was very depressed and sad because he lost you.
Time skip 15 years now, you were looking very different from your highschool times living in the island after knowing everything for this many years now.
You were roaming around the edge of the beach looking for something when suddenly you saw a person walking towards you with a apron for cleaning of island.
The man was wearing glass and was quite taller then you, you were shocked to see a human after this many years.
You grabbed the person's face looking to confirm if his real or not, the person looked at you shocked of what you are doing here.
