A/N: Bold letters are spoken in Tagalog.

"Boy, if you don't listen here-" "I don't care, you Dumb Scientist." "Don't just cut me off! I'm in class, you dumb fuck!" Senku chuckled as Y/n kept whispering to him, trying to keep a straight face while doing so. Her blazer was covering the cracks on her neck so no one will notice.. "What subject are you on to right now?" Y/n grumbled. "Araling Panlipunan." Senku blinked.

"Uh... How do you pronounce that?" Y/n sighed which caught her seat mate, Lavender's attention. "Hm? What's wrong?" Y/n shook her head as she looked boredly at her worksheet. "I hate this subject so damn much... And how the hell do you even get these things so easily?" Lavender chuckled as Senku was still impatiently waiting, tapping his foot as he was writing a hypothesis on dirt while sitting down on a rock. "I just do, what's the deal? " Lavender laughed as she got back to answering her worksheet.

Senku grumbled. "So? How do you pronounce that? What subject is it?!" "Ok! Ok! Calm the fuck down!" Y/n whisper yelled as Senku laughed. "In other words; it's history. We call it Araling Panlipunan here in the Philippines, idiot." Senku grew a tick mark. "I'm not a damn idiot, you are!" Senku retorted as Y/n his her smile with her hair. "God damn you, Senku."

Ma'am Coleen hit her table 3 times which gained their attention. She handed out her hand. "Pass your papers." Senku smirked. "Looks like your teacher's a pain in the ass just by the sound of her voice." Y/n nodded and passed her worksheet in front. "Here you go... Of course she is, but I think she's scared of me though, knowing I'm the Lifeless Queen here in the school who's a Science geek."

Senku just snickered at her given nickname. "Lifeless Queen? Why do you have that nickname? I think it's because you're too blunt." Y/n smiled, a murderous aura surrounding her which scared Lavender and the other students. "Y-Y/n? You ok, girl?" Y/n looked at her with her most murderous smile, they all flinched at her face. "Of course! I'm fine! " She said sarcastically, Senku was laughing like a maniac as she stood up with her bag and stormed off the room to head to the roof.

"I- that's the first time we saw the Lifeless Queen smile..." A student nodded. "But it's not a sincere or a playful one, she's really scary..." "I bet that the one who made her angry will be found dead in a few minutes..."

"Damn you, Senku, I'm not blunt! Not me! You're the blunt one!" Senku raised a brow. "Oh? Nah, I'm the most logical Scientist out there!" Y/n crossed her arms while walking. "Says the one who divorced Ruri not after 5 minutes!" She whisper yelled which made Senku turn red. Y/n laughed as she arrived at the roof. "Now what? I shut you up, didn't I?"

"Whatever!" An awkward silence took over as Y/n ate her packed lunch silently as Senku was still making his hypothesis on the dirt. "Still having that dream?" Senku nodded as he sighed. "What if... This shit's real? Y'know, that prophecy and stuff..." Y/n just shrugged as she drank her cola. "I don't know, that'd be hella cool though but dangerous at the same time, so much blood was scattered, it made me want to puke." Senku laughed at her. "Yeah, maybe..." "Yeah, then me and you will be the Tristan and Malia like in that prophecy if it really is real. Then we'll be lovey dovey after the war, 'yiieee, they're so sweet!' That's what they'll say about us." Senku dead panned while Y/n's heart seemed to have beaten faster than before after mentioning that there's a possibility that they'll be together.

"I got none of that, speak more normally, dumb ass!" Y/n laughed as she looked out in the horizon while eating her lunch. "Nah, it's better if you didn't know..." Senku's eyes widened. "That's not fair! You know all three languages and I only two! English and Japanese!" Y/n shrugged as she popped rice in her mouth. "Better study Tagalog next time, then." Senku gritted his teeth as he looked at his new hypothesis. He smiled.

"Sure, I'll do that once we de-petrified everyone in the Philippines. Though, meeting the ones back at your world might be more amazing." Y/n laughed lightly, the sound echoing down the stairwell as Lavender heard it. "Well, me and the villagers will be collecting silkworms for silk clothing, see ya in a bit." Y/n nodded with a smile, her fork still in her lips. "Yeah, whatever, Leek-Head. Bye." "Bye." They both disconnected as she cracked her neck, she felt a little crack on her skin disappearing after she disconnected with Senku.

"What?" "Y/n! Why'd you run out like that all of a sudden?!" Y/n flinched at Lavender's voice to see her in the doorway of the stairwell. "Huh?! Oh, I just... Recalled the most embarrassing thing I did in elementary... Don't even dare ask me about it!" Lavender giggled as Y/n packed her lunch box back at her bag as Lavender went to the volleyball club and Y/n went to the Science club to see the club members working already.

They all turned to Y/n st the sound of the door opening and greeted her. "Welcome back, President!" Y/n just nodded and put on her lab coat. She went to her station to see that it was clean. "How was your progress while I was gone?" "Fine and qualified!" They all answered in unison as she started to sprinkle Calcium Carbonate on the rice they're were growing with surgical gloves.

"Good to know, did the basketball team come in here?" "No, ma'am!" Y/n rolled her eyes as she put on her goggles. "Don't call me ma'am you idiots, I'm still the same age as you." She scoffed as they all apologized. The door slammed open and they all turned to see Joyce holding her phone with the picture of Y/n the press took when she was departing from NASA. Her eyes widened.

"Shit, I forgot about that..."
