What should I do now since Naeun is at college in the story?

• Continue both Myungsoo and Naeun's point of views [this will be boring though]
• End the story and start a sequel with Naeun at college and Myungsoo at 3rd yr HS
• Time Lapse after Myungsoo graduates from High School
• Introduce another character for Naeun since she is away from everyone else.
