Mattsun was waiting near the front door of his complex. His eyes couldn't keep off the clock as he checked several times. His little sister had gone on a date with his good friend Kei and he couldn't bring himself to just let her come home late with him. It was 10 minutes past the time she said she was going to return. Like the protective big brother he was, he waited thinking about the things he would say when she came home.

Without another second, the door began to jiggle. Unlocked, the door pried open revealing Nozomi with Keiichi behind her.

"You're still up?" she asked a bit shocked to see Mattsun waiting like a father in the living room. Without a hint of sympathy he stated "You're late. I couldn't sleep knowing you were out at night with Kei" he stated.

Kei on the other hand, unphased at all, just laughed and walked Nozomi further into the house.

"Don't worry Mattsun, I didn't do anything to her" he said while patting her shoulder.

"I had a good time okay? We should hangout again sometime" Kei stated, this time only towards Nozomi.

Nozomi, being the lover she was, sprang to life and nodded.

Just before Mattsun could interfere, he received a call. Taking his phone out from his pocket he examined the contact slowly.

"Anna? Why would she be calling me so late?"

As soon as the call came through he jumped into action, grabbing a jacket and sprinting out the door.

"Don't do anything while I'm gone" he shouted down the hall towards the two lovers left in the house.

"Thank you for coming at such a late hour" Anna said with a relieved expression. "She's had a bit too much to drink...we were celebrating my promotion and I think she exceeded her limit because of stress" Anna claimed while directing him in the direction of the dark haired female.

Glancing over Anna, Mattsun could see Mari on her "who knows what number" shot of sake.

"Alright spit woman, party's over" he laughed trying to lighten the mood. Mari only glanced at him as he placed his arms around her waist, lifting her to stand.

"Who the hell are you" she slurred her words.

"Idiot, I'm your boyfriend" he said spacing his words so she could understand.

"Oooooooh Matttt-suuun" she said poking his forehead. "I'm fine I'm fine", clearly she wasn't.

He managed to pick her up bridal style which was difficult at first since she was kicking and screaming to come down. But once he walked outside, her shrieks turned to shivers as she clung to him for warmth.

"See you later Anna, I'll call you when we reach her house" he said while propping her in place.

(Who knows how long it took them to get to her house realistically. But for the sole purpose of this story let's just say it wasn't that long)

Once he got into her house, he carried her towards her bedroom. Mari, being intoxicated as hell, was still drunk. He called Anna like he promised, and made sure Mari was drinking enough water to sober her up.

"What was so stressful that caused you to drink this much?" he asked while lying next to her on the bed. He didn't expect her to answer, but she did.

"I'm struggling in school"

"So am I, but you don't see me getting shit faced" he teased, one hand holding up his own head, the other comforting her. She was still cute even when she was drunk, he thought to himself.

"Mattsun…" she said in a sweet soft voice. It caught his attention, especially since he was used to her throwing venom with his name.

"I'm here" he assured, brushing her hair once again.

"...I miss you a lot" she slurred silently at first, and then her words became louder. "I get jealous of those girls who come around! Don't they know you're mine?!" she stammered. Her drunk frustration entertained him.

"Oh? This is the first time I'm hearing this" he laughed.

She only nodded her head (she couldn't hold herself up straight). "You're so good to me…" she said resting her face closer to his.

"I know I know" he said proudly. "You should open up to me more like this when you're sober" he laughed while cuddling her small body into his arms. Nuzzling her head through his arms she smiled.

"Kiss me"

"What?" he shot back so fast. Don't get him wrong, he wasn't complaining. But he hadn't kissed her since the first day they met.

This time she said it more shyly. "Kiss me".

"Mari-chan, you're a little drunk right now" he laughed, making a joke that she was actually a lot drunk right now. "Ask me in the morning when you're feeling better" he said sitting up, but of course he was pulled back down.

"I'm asking you now~" she chimed.

"Why do I have to initiate?" he smirked. Stunned, Mari began pouting, something he wasn't used to seeing.

"Fine". Instead of giving up, she took him by surprise, placing her hand against his face and kissing him. Once they broke away Mattsun could barely function. Her lips were soft and plump, leaving a small essense of sake he could taste. His face was red as a tomato, thank god for the darkness.

"There. Maybe now they'll stop" she stated confidently. It took him a few moments to realize she was referring to the girls at school.

"Dummy, they're not here right now" he smiled while tapping her head lightly.

"I know...thank you…" she said, this time her words became lighter as she became sleepier.

"I love you Mari~" he cooed into her ear.

Unfortunately she was so tired that she passed out against his chest, unable to hear him.

Ayyy, why does this girl put me in these kinds of situations!

He screamed in his head as he was still flustered.

A/N: I'm screaming lmao they're so cute I cry! Wowowow I posted two back to back real quick. I felt that my last one shot wasn't enough lol. Don't mind me as I write at 2am, getting inspiration as I sit in bed hahaha. More to come in the next few Mattsun x Mari oneshots. Let me know how it is! :-)
