You and your childhood friend had been friends for 6 years, in the last moments of your 6 years you decided to confess to him. Only to be politely rejected, it hurt but both of you still stayed as friends. But that wasn't the only thing happening, you didn't tell Kae that you would be moving before confessing your love.

You thought it wouldn't be nessecary considering how heartbroken you were that time, fast forward to some more years later you found out his and his family will pay a visit.
