Baekhyun leads a quiet life as a relatively successful author, but when his editor tells him to baby-sit his hybrid, Sehun, for a few days, Baekhyun’s life turns on its head, causing him to confront his self-doubt and accept the risk of heartbreak that comes with caring for others.

When Baekhyun loses a bet, his punishment is to buy a ridiculous amount of condoms at his local convenience store in front of the cute cashier, Chanyeol.

Chanyeol has a crush on Baekhyun and everyone knows except him.

After moving in to a ridiculously large and lonely house, Jongin meets a mysterious boy with striking black hair and a sharp wit who interrupts the monotony of his rigorously organised existence.
