From Yen Press:

It was love at first sight. The moment Hee-So’s eyes met Won-Jun’s she knew it was meant to be. Their relationship took off when Hee-So confessed her feelings on national TV, but less than a month later, Won-jun is ready to call it quits without any explanation at all. Hee-So’s had a lot of boyfriends — Won-Jun is number twelve — but being dumped is never easy. She’s not ready to move on to the thirteenth boy just yet. Determined to reunite with Won-Jun, Hee-So’s on a mission to win over her destined love once more.
