You and Izana are good friends until you confess your feelings to him when you turn 14. (Your 4 years apart.)

But you got rejected coldly. You become devastated, and decided to move on from him.

Days passed when you left. He started to miss your voice, personality, the way you smile and hugs.

He realized that he actually have feelings for you, but it's too late. So he do everything he can to have you back, even he has to travel to your home country from across counties.
