Donghae has always been that kind of person who couldn't stand loneliness. At all. Yet it was so hard to find someone who will understand him and won't run away after learning about it. The guy thought he was lucky enough to meet Hyukjae... even though he actually always had Heechul beside him.

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?

What can happen to the complete strangers who had to share the same umbrella on a rainy day?

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 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

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.
