2/2

"Dear Sanemi, how do you handle (Y/N)'s jealousy?"

"Well, she doesn't show her jealousy a lot and it's hard for me to know when she's jealous. The only way I know is when there's a sword 1mm to my neck. Or when I start choking on my poisoned drink. Or when I'm invited for a 'bros' night with her cousins. Or until I somehow remember my past life in my next life."

"Are you sure you're okay?" Sanemi asked as he set down their food on the table. It was currently lunchtime and (Y/N) decided to spend some time with her boyfriend in the faculty lounge since their relationship would be a bit too... scandalous...

"Yeah..." (Y/N) nodded with a sad smile. "I just had a troublesome day is all..." She flashed him a smile but Sanemi knew that it was fake.

"Are you sure? You've been looking down these past few days?" He asked as he watched her play with her food. "Did... did I do something wrong?"

"Oh, no!" She exclaimed, waving her hand in front of her. "You didn't... do... anything wrong..." She muttered as she stood up, closing the lid in her lunch box. "I-I'll get going... I'm not... hungry anymore..."

As (Y/N) left, Sanemi watched her retreating back. And just as he left, another student entered and handed something over to Kyojuro before running off with a red face. Kyojuro then took it, walking over to Sanemi with a small frown. [CODE-MOTHER-FUCKING-RED! RENGUKO FROWNED!!! AAAHH-]

"Shinazugawa-san..." Kyojuro handed the small paper bag that had a small note with a little heart on it. "I think that you should go talk with (Y/N)-san..."

"Why, what's wrong with her?" He asked, feeling weird with all the stares his co-workers were giving him. He took the paper bag and placed it in the corner of the room where there is already a pile with all the gifts the teachers are getting from the students.

"You..." Uzui sighed as he went back to his lunch. "Just... Just try to understand why she suddenly ran off." For once, Uzui didn't give a remark, which left Sanemi confused.

"What, (Y/N) is not here?" Sanemi asked as Kanae and the other teachers nodded. It was the next day and it was lunch. (Y/N) usually comes to the teacher's lounge to eat lunch with Sanemi, but she wasn't there today.

"But, (L/N)-san's cousin came and said that this was for you." Himejima walked over to his desk, setting down a bento that was wrapped in pink with hearts.

Sanemi glared at the box in front of him. Never had (Y/N) made him a bento that had this style. It was always normal looking. He opened it and saw a note inside that had a little heart in the corner and he was really starting to get worried.

"Wow, (Y/N)-san is very nice to leave you a note and a bento!" Kyojuro said, peering over Sanemi's shoulder. The others came as well to see.

Sanemi shook his head as he took the note. "She doesn't make things like this..." HE trailed off as he opened the note.

"Have fun today in school, darling~

I prepared a little something for you!

Sorry for not coming today, I just feel like shit because of your stupidity.

I hope you choke on your food.

Without love

-not (Y/N). These are her cousins. Watch your back."

Everyone had their mouths open as they saw the note that was written in ragged writing. This was not (Y/N). Sanemi gulped as his shaky hands set the note down gently, fearing it might explode or something.

He took hold of the lid, the others hiding behind him. And... he opened!

"It's... surprisingly normal." Sanemi said as he looked at the perfectly cooked food with perfect attention to detail. He set the lid down and another note fell off. This time it looked normal and he recognized (Y/N)'s writing.

"Hey, Sanemi.

Sorry for not coming today. I'm ---

I'm fine so don't worry too much.

I made you this. I'm pretty sure that Michikatsu probably won't put poison in it this time. Probably. Sorry if he did.

-(Y/N)"

That was all the note wrote and he squinted at the food in front of him. But he was sure it was (Y/N) this time. The handwriting and the little scratch on the letter was obvious.

"Are you sure that it's not poisoned?" Uzui asked as he looked at the perfectly made bento. "And she said 'this time'. Did this happen before?"

Sanemi placed the note down as he nodded and took a pair of chopsticks. "Yeah... around... two months ago... I think." He said as he took a piece of food and placed it in his mouth, satisfied that it wasn't poisoned this time.

"Two months ago..." Uzui whispered, giving a side glance to the others. "Isn't it that one time a student confessed to Shinazugawa in the cafeteria with all the streamers and shit?" The others nodded, trying to get the message across Sanemi. "DUDE! WE'RE SERIOUSLY SLAPPING YOU WITH INFORMATION AND YOUR STILL DENSE AS FUCK!"

"What do you mean?" Sanemi asked. Uzui screeched as he left the room, telling the others to tell him the problem.

"Shinazugawa-san," Kanae began as she glanced at Sanemi with a disappointed look. "(Y/N)-chan is jealous." Sanemi's eyes widened as he finally realized and the others rejoiced, Uzui was listening behind the door. "She went here yesterday hoping that when that girl came she'd see her and you eating lunch, but she got scared that it might start nasty rumors about you so she left before that girl could come."

Now Sanemi felt horrible. He should've noticed, what kind of boyfriend is he if he can't even notice when his girlfriend is feeling sad and jealous. "Oh fuck."

═══*.·:·.☽✧ ✦ ✧☾.·:·.*═══

The moment the school bell rang, Sanemi rushed to the faculty office and just swiped all of his work and made a dash for his car and just threw everything in there. He rushed his way to the Tokito residence.

The gate then opened by themselves, as if expecting Sanemi to arrive. Once he parked, he immediately rushed to the door where it opened by itself. Inside were (Y/N)'s cousins. Yuichiro, Muichiro, and Koichi all somehow made it faster than Sanemi did.

All of them were holding swords and giving Sanemi an empty stare. Michikatsu was at the dining table, sitting down, tapping his fingers on the table. Yoriihchi was on the stairs, his arms crossed. The twins were leaning on the couch with Koichi sitting on the couch. He knew they wouldn't kill him. Probably.

"So?" Michikatsu raised a brow. "How long did it take you to realize?"

"... long enough." Sanemi answered as he gulped, feeling scared with the dark atmosphere. "Is... is she okay?"

"You tell me." Yuichiro scoffed.

"(Y/N)-nee didn't even eat last night." Muichiro added.

"Nee-chan has been in her room since yesterday and only came down to prepare our lunch." Koichi said as he glanced over to Yoriichi.

"If we hear her cry or anything, we're rushing up there." Yoriichi said as he stepped out of the stairs and Sanemi immediately ran up.

Once he reached the third floor, he went over to (Y/N)'s door and immediately went inside. The moment he saw (Y/N) sitting on her bed, on her hands was Shiro who was giving his mother a hug. "I said I'm not hungry... go away..."

"(Y/N), it's me, Sanemi." Sanemi stepped closer but (Y/N) didn't even respond. He sat down at the bed, Shiro following his every movement.

"Daddy bad." Shiro said, holding into (Y/N) as tight as his little hands could do. "Mommy is sad. Daddy bad."

Sanemi felt worse now. Even his own son was telling him off. "Yes... daddy was bad." He said, taking Shiro and setting him down in his lap who tried to get off and calling for his mommy. "(Y/N)..."

Shiro managed to wriggle out of Sanemi's hold, returning to his mother. "Daddy bad."

"Yes. I get it, Shiro." Sanemi groaned as he lightly pinched his son's cheek. "(Y/N), can you please look at me." There was a second of silence until (Y/N) finally looked up, but ignoring Sanemi's eyes as she stared at the ground. "Were you... were you jealous?"

"Yeah..." She answered quietly, Shiro going inside her hold again. "I'm sorry, I'm being selfish... I just wanted..." She paused, almost as if contemplating what to say. "I'm sorry... I almost..."

Sanemi knew what she was trying to say. He scooted closer to her, pulling her in a hug. "Hey, it's alright to be selfish. It's part of being a human. And just so you know, I don't plan on dating anyone else other than you. Plus," He paused, ruffling Shiro's hair. "We already have Shiro. Why would I leave you two for someone else?"

(Y/N) felt tears well up in her eyes but she wiped them away. "I'm sorry... I just get jealous when other people confess to you... I just get scared..."

"Stop apologizing." He said, pulling away from the hug and kissing her tears away. "I told you it's alright. I want you to do what you want if you're being jealous. Don't run away and hide. Got it?"

"Really?" (Y/N) asked, the little shine in her eyes was back and Sanemi was happy to see it again. Sanemi nodded and asked what she was actually planning to do. "W-w-well... U-uh... I... I might or might not have been planning on kissing you in front of that girl."

Sanemi chuckled, taking her in another hug, showering her with kisses while she and Shiro struggle to get out. "Next time, just tell me, then I'll make sure to give you all the attention in the world."

"Is daddy good now?" Shiro asked, pinching his dad's face. (Y/N) nodded as Shiro smiled, taking his father into a hug. "Shiro wants choco."

(Y/N) chuckled, taking the small container of chocolates from her night stand, but before she could open it, her door burst open and Michikatsu and Yuichiro entered with angry looks.

"NO! SHIRO ALREADY HAD CHOCOLATES!" They exclaimed, making Shiro pout. His lips began to tremble, his eyes getting glossy. "That doesn't work on us young man." They said.

Shiro clicked his tongue. "I like uncle Genya, Yochii, Mui and Ko better."

(Y/N) and Sanemi watched with smiles as Muichiro, Yoriichi and Koichi grinned from ear to ear in the doorway, being called the favorite uncle and all.

Sanemi leaned on his arms as he got close to (Y/N)'s ear to whisper, "I'll spoil you tonight."

They fucked, the end!
