Hidden secrets, painful pasts and happy endings. That's usually how it goes, no? Maybe not, Hyukjae quickly learns. Meet Lee Donghae, a twenty-five-year-old man-child with the mentality of a five-year-old; Hyukjae's best friend. A big, childish baby who

Hyukjae isn't human, and Donghae knows his secret.

Flowers are beautiful, aren't they? Sometimes they bloom in the harshest of conditions, fighting for the chance to paint the world in a myriad of colours. What matters is that they survive and continue to bloom, regardless how difficult things may be. Akin to the love Hyukjae and Donghae feel for each other. Not a single day goes by where they aren't thankful they'd crossed paths, that the

In which Donghae makes one of the biggest mistakes in his life, and Hyukjae and Donghae learn that sometimes, the pain that comes with falling out of love is irreversible.

They're born just days apart. Heechul is, unlike his usual self, all out to make sure Leeteuk's birthday is special this year. Cue a little dinner and several confessions, and the night feels younger than they've ever been.

Donghae has developed a love for Dyson vacuum cleaners. His first day with a new vacuum cleaner.. .

Donghae earns a living by working at a diner. Hyukjae earns a living through crimes. One brief encounter and they're both living life on the edge after Hyukjae learns that Donghae is a kleptomaniac, but commiting crimes never ends well. Hyukjae and Donghae are no exception.

Lee Donghae is an amnesiac. Following an accident that kills his parents, he trudges through the next few years trying to piece his past together. On an afternoon by the waterfall, a redheaded man approaches him, presenting a key that unlocks the Pandora's box to his lost memories. Does he take it?

Years pass, and yet love remains the same. Or at least Taemin thinks, until he realises that maybe, just maybe, Hyukjae and him were on different pages all along.

The first time they'd met, Donghae was merely a party magician, and Hyukjae, the father of the birthday girl. Fast forward fourteen years, they find themselves sitting in a cafe they'd visited ever so often in their courtship, celebrating the love they'd shared after all this time. Donghae finally finds the answer to a question he's wondered about all this while.

Before the pain, there is pleasure.  Taemin very apathetically awaits the arrival of the new student. He isn't looking forward to sharing his living space with a stranger, to be honest. Or at least he thinks he isn't looking forward to it. However, in walks scrawny, youthful, redheaded Hyukjae, who might just change his mind. Unfortunately, this isn't a love story.

For little Eunji's fourth birthday, single dad Hyukjae throws her a birthday celebration with the help of his best friend, Siwon, who helps plan the party. Much like Eunji, Hyukjae too, receives a present by the end of the party. A rather large one, in fact.

Yesung and Kyuhyun have spent the last decade of their lives celebrating their anniversary in the exact same manner; they'd settle in the same restaurant several blocks down from where they lived and reminisce. Would this year be any different?
