Alina looked up from her laptop as she heard the front door swing open. She looked outside her window and saw her brother Matt and his friend Mike coming in. Alina looked down and blushed, she had had a crush on Mike ever since he had been invited by Matt over for dinner about a year or so ago. He was always so kind to her every time he saw her as well as being one of the hottest things she'd ever seen. She put those thoughts aside before staring hopelessly at her unwritten essay, it was almost as if the laptop was laughing at her procrastination levels. She went down on her bed and sat down with her laptop and attempted to write the essay. She was successfully halfway through her first paragraph until she heard a knock at the door, before seeing the door slightly open. But what she hadn't done was prepare for what was about to happen.

Alina's POV
"Hey, Alina" Mikey smiled, coming into her room. Oh my gosh, I could feel myself going red.
"Hi Mike" I said, blushing. I was a hot, red mess at this point. And I'm pretty sure I knew that.
I signalled him to come in so he came in and sat down on my bed.
"So, whacha working on?" He said, looking at my tiny paragraph.
"Well, I'm attempting to do my history essay, but it's proven to be harder than I thought......"
"Ah, I see. And I'm sure watching 13 reasons why will definitely help" he smirked, pointing at the added tab on my screen.
"For you information....... yeah I've got nothing" I laughed. God, I'd pay to see that smirk everyday.

"Well, if you'd like, I could help?" He suggested.
"Oh yeah, sure. But make sure my essay lives up to your D+" Alina teased, making Mike laugh.
"Hey, I didn't get a D+! I got a D-!" He laughed. "And anyway, history isn't even my strong subject"
"Ahh, I forgot, you got a solid C in sport didn't you" Alina laughed earning a pillow on the head from Mike.
"Actually, I got a B in sport. But I forgot, we can't all live up to Little Miss Alinas straight A's" he laughed.
"Yeah, not a lot of people can" she shot back. But as soon as she felt herself typing away, she also felt tickling fingers skittering up her sides. Alina's arms let go of her laptop as her arms shit down in defence.
"NOAOAHAHAHHAHAHAHHHAH, MIKKKKEEEEEEEE AHAHAHAHHAHAHAH, NOAHAHAAHHAHAHAHAH" she laughed trying to push his arms of, but it turns out that B in sport wasn't doing Alina any favours.
"I'm sorry, we're you calling my dumb!?" He asked as he snakes his hands round her waist, causing her to be more immobile. All Alina could do was shake and wriggle while her giggles filled the room.
"See, this is where your straight A's don't do you any favours" he teased as his fingers found her stomach which made Alinas giggles go up into a whole different pitch. She threw her head back in laughter as she was tickled by her crush. And her face was turning a shade of red, partly because of all the blushing and the fact she was being tickled I her worst areas. As if Alinas luck couldn't get any worse, she heard the door open, and in walked her brother Matt.
"Woah, Mike, what has she done?" He laughed sitting next to a struggling sister.
"Little Miss Alina basically called me dumb"
"I DID NOT, I JUST SAID-
"Well she can't be that smart if she managed to get into this position" interrupted Matt. "But, Mike, your tickling her in the wrong place." Before there were any protests, Matt, knowing his sisters worst spot, darted his fingers to her ribs, scribbling them up and down, receiving high pitches shrieks. Matt, knowing dodged Alinas flailing arms but continued to tickle her while she screamed for mercy.
"NAHAHHAHAHAHAHHAHAHHAHAHAH, STOAOAHAHAHAHAHAHHAPPPPPPPP MAAHAHAHAHAHHAHAHAHAHTTTTTTT, ILLLL KIIILLLLLL YOUUUUUUHUHUUUUU!
"Yeah, good luck with that Ally, how do you plan on doing that? He asked.
"MIIIIIKKKKKKKEEEEEE, PLLLEAHAHAHSSSEE HAASVVVEEEEEE MEERRRCCCYYYYYYYY" she screamed of laughter. Tears were threatening to fall, while she shook her head in laughter. But in Mikes strong grasp, she wasn't going anywhere.
"Hey we'll let you go if you say.......... Mike and Matt are way smarter than me" Matt laughed. Although Alina's incoherent speeches weren't translatable, she gave it her best shot.
"MMMIIIKKKEKEEEEEE AHAHANNNDDDD MMAAHAHAHTTTTTTTT AARRREEE WAAAYY AHAHAHHAHAHAHAHAHHAHAHAH" she wasn't able to finish her sentence, because Matt stuck his finger in her belly button which made her go into silent laughter.
It was only until they shared a grave that they sense she had had enough so they bother decided to stop.
They let her up and she glared at them both refusing to look both of them in the eye.
"Alright, alright, I see you got an A in drama as well! What do you want?"
"Sweets and chocolate?" Alina innocently smiled and battered her lashes at her brother which she knew he couldn't resist. He sighed and went downstairs to the kitchen.
"What can I do?" Asked Mike. He didn't get a response but he continued anyway. "Well, what I would love is, if you would like to go out with me sometime?"
Alina snapped her head round forgetting about the silent treatment she was meant to be giving. She felt herself blushing, then again when isn't she when he is around?
"Yeah, I'd love to" she smiled at him, trying to hide her excitement when in reality she was doing her victory dance in her head. I've been waiting for this moment for my whole life she thought to herself.
"Sorry, what was that?" Mike laughed. "Did you just say you'd been waiting for this moment for your whole life?" Alina looked down in embarrassment, how could she have said that out loud?
"No no, don't look like that!" Mike said, half laughing but half concerned.
"But why me?" Alina said, still embarrassed.
"Why you? Isn't it obvious, I've had a crush on you ever since I'd met you!" An awkward silence filled the room, but Mike broke it. "So, you still up for that date? We just need a way to tell your brother!" He laughed which wasn't a laugh from Alina.
"Tell me what?" A voice said from the door. There stood Matt holding the sweets and chocolate.
"Well, umm, Mike and I are....... we're umm going on a date?" Even though it came out more as a question.
Matt looked at them both, not sure what to say, but he soon broke out into a smile.
"I mean, it's better than her dating some fuck boy!" He laughed sitting on the bed.
"And plus, I personally don't think anyone could stand this laughter" he said as he dug his 10 fingers into her sides, which made Alina produce her infamous giggles, along with Matt and Mikes laughter.
