Choco Celestina Latte, a graduating student of Psychology, keeps receiving letters from a stranger. It doesn't have a name nor an address. She's on the bridge of moving on, from Tristan Sbarro, the guy who left her, when she met Belgian Clyde Waffle, a man of mystery. A man who helps her realize what she's been missing for years of her existence.

She's still holding to their promise that they'll love each other until eternity. Can she keep that promise and stay loyal to him or indulge herself to fall for someone else?
