"bye guys, enjoy your vacation..." donghyuck waved at his five friends leaving for their five-day vacation. taeyong had been strict about it, and he had eventually accepted it.

flashback:

"i am very sorry. donghyuck is in danger and we need to have him in this house to protect him."

"but dream will be with us, they can protect me!" donghyuck whined.

"dream is in charge of protecting renjun, because he is in danger as well as he is your bestfriend."

"huh?" renjun questioned.

"i told you i could protect myself, please... it's for five days only."

"donghyuck. i need you here. plus, you just got beaten up by mark and he is on your side so he hit gently. imagine being out there with people who try to get you killed. you won't survive."

"because people are trying to kill me?!!" donghyuck screamed.

"that's not what i wanted to say- anyway. you can't go."

end of flashback

he was saddened at the sight. what a good way to start the holiday he told himself.

closing the front door, he got face to face with three young chinese boys.

"hey donghyuck..."

"...since we know how sad you are because of taeyong's decision..."

"...we decided to bring you to our lab to make funny experiences!" they said, finishing the sentence of the other.

donghyuck giggled at their cute behaviour and nodded in agreement.

they crossed the living room, passing by mark who was staring blankly at the turned off television.

"try not to make everything explode this time." he said nonchalantly.

"we'll try, but can't promise!" yangyang exclaimed before pulling on a book in the library, making a passage open.

"i swear this house is magic." donghyuck gasped walking in the secret passage with the three boys.

"yeah, we tried playing hide and seek there once." xiaojun started.

"we lost yangyang for two days." hendery finished. "these were good days" he added whispering and then laughing with xiaojun.

XXXXXXXXXX

"blondie!" donghyuck whined for the nth time of the hour.

"i told you to leave me alone!" mark groaned, taking his head in between his two hands.

donghyuck had spent most of the day in the house's lab with hendery, xiaojun and yangyang. they had taught donghyck how to create bombs as well as other cool products that could burn metal of make things melt. well, donghyuck had learned more science in a day than he had during his whole scholarship.

but now, wayv had been called to go on a mission, so donghyuck was left alone. that's why he got to mark's room, entering even though the older had told him not to.

"but i'm bored..." donghyuck rolled on mark's bed.

"go annoy someone else. and don't stay on my bed like that! you'll undo it."

"but you're the only one who's my age! and the others are busy."

"well, i am too." mark spat.

"doing what? smoking? that's not what i call being 'busy', you can still take care of me."

mark crushed his finished cigarette in the ashtray.

"i don't do 'take care'. never. and i don't want to."

donghyuck chuckled, approaching mark and snatching the pack of cigarettes from his hand when he was about to take one out.

"then come after me!" he smiled brightly before dashing out of his room, mark's treasure still in his hands.

"come back here, fucker!" mark roared following him at the same pace.

donghyuck ran all around the house, sometimes getting lost in the corridors, but eventually losing mark when he got to the living room and kitchen area.

he screamed in joy and tucked the cigarettes in the back pocket of his jeans, turning around to make sure mark was nowhere around. what he didn't expect at that exact moment was to get hit right in the face by a bouncing ball. thank god it hit his cheek, because if it had touched his nose, it would have been a disaster...

"not only do you suck at fighting, but you have very poor reflexes as well." mark sighed, standing up from behind a buffet.

"that's rude of you, blondie." the younger replied, throwing it back at mark's face, but missing him of a meter.

the ball hit the buffet and bounced around the room, before mark caught it effortlessly.

"well, you don't know how to aim as well..." he added to his list.

"shut it! at least, i am not an emo kid part of a gang!" he defended himself, pulling out his tongue at mark in a childish manner.

"i am not an emo kid!" mark roared, making donghyuck burst out of laugher.

mark walked angrily towards him, not scaring donghyuck a bit.

"of course not, blondie." he giggled, making mark angrier.

the older approached donghyuck, this time scaring him, because the childish boy walked backwards until his back encountered a wall. he gulped at mark who trapped him between the wall and his two muscular arms.

"my name is mark, annoying piece of shit." he growled, voice so deep that it sent shivers to donghyuck's spine. "by the way... i think you still have something that belongs to me?" he questioned looking into donghyuck's doe eyes.

donghyuck nodded "i-in m-my b-back p-pocket." he stuttered more than ever. mark was intimidating, and having him this close didn't help anything.

"let me get it." he smirked, letting his hand slide from donghyuck's wait to his butt, passing the hand in donghyck's pocket to take out his stress reliever. donghyuck got red at his actions.

mark kept their position, even after getting what he wanted. he kind of liked having the younger this embarrassed and this submissive.

they looked each other in the eyes before being interrupted by a door opening, just next to mark's hand that trapped donghyuck.

"oh! i'm sorry. did i disturb something?" yuta said, making mark leave quickly and donghyuck even more embarrassed.
