"You know how we could really become sisters? If you marry Jisung." Marry her best friend's brother sounds like nothing but a funny, annoying joke to Yena for years. Marrying Jisung? The thought is ridiculous - he's older, experienced, and probably only sees her as a child anyway. Until Yena starts to actually fall for Jisung, quite by accident, and suddenly become sister-in-laws with her best friend doesn't sound like such a bad idea after all...

A month's trip to Japan sounds like a perfect break for Dami - big city, small villa, surrounded by her family. That is, until, she realises the month will be spent with her ex boyfriend whom she hasn't seen for the past five months. Dami and Minho mask the perfect couple in front of Dami's family, blatantly ignoring the past five months of tension and unresolved feelings. But, amidst pretence and reality, messy feelings and unsaid words combine, and soon they're not so sure it's pretend anymore.
