As a pixie, Donghae dreamed to make miracles. As a human, Hyukjae dreamed for those miracles to happen to him. As two lonely souls, they finally found miracles in each other.

If you asked Hyukjae whether he believed in mermaids and mermen, he would've said a solid 'No'. However, even he still believed mermen are creatures that know how to swim. But what if he meets a merman who doesn't?

Their relationship was simple when they pretended it was love and met only on Saturdays. However, it's only natural that you start wishing for more over time you spend together. Will this game of the two pretending it is love turn into something bigger?

If someone asked Hyukjae to give a definition to the word ‘unfortunate’… he’d definitely say, “Donghae.” If it’s about him baking something, he’d burn the food. Reading the book? He’d cut his finger with pages

Donghae died. And was brought back to life. He probably wouldn't believe it either if it didn't happen to him. Just like he'd never believe that Hyukjae, the classmate he never really talked to, will be the only one who won't be scared to talk to him and won't call him 'Zombie'.

What started from a wish to help, from that wish to make someone whom Siwon cherished to feel better... led to feelings him and Donghae never expected to develop after so many years spent together.

Hyukjae is known for needing some 'me time', maybe a bit more than others do. Donghae is known for being so clingy, to the point one can call it abandonment issues. They're painfully different, yet make a beautiful couple for more than one decade. How?

"How about a smile for good luck?" Hyukjae would ask Donghae every time he needed some reassurance. "Even if it won't work, at least I'll get to see you smiling." Donghae would give his smile to the other guy every time he needs it. But here comes the day when he stops, and so Hyukjae is unable to see it anymore.
