"When you are alone and miserable—remember this was the moment you threw your happiness away."    They were supposed to last forever, but everything changed as soon as Chanyeol broke Baekhyun's heart— leaving it battered and almost beyond repair.

Baekhyun is madly, deeply, and irrevocably in love with his childhood bully, Park Chanyeol— who jokingly  promised the petite brunette to love him till he was 70. 

They were supposed to last a lifetime.  Just like how they always promised each other.

All Chanyeol ever wanted to do was to make Baekhyun feel wanted. 

Byun Baekhyun took everyone in his school by a surprise by saying "yes" to a certain big dumb giant.  And yes, by everyone, I meant everyone. Including the elder janitors.  Who would have thought that the Byun Baekhyun would go out with Park Chanyeol?  The guy who had the biggest and goofiest smile in the school.
