Illogical (Senku x reader)

💕Special! ~ What if?💕

"Shall we get ice cream?" [Y/n] asked, and Senku chuckled.

"Sure."

On their way home, [Y/n] and Senku stopped at a café and shared an ice cream sundae. "You know, Senku," [Y/n] began, "If you don't feel comfortable with me going out with Tsukasa-san, then I'll cancel."

Senku took his head. "You're free to do whatever you want." He said. [Y/n] wasn't entirely convinced, but she decided to change the subject.

"So, when will Byakuya-san be coming home?" [Y/n] asked while scooping ice cream in her mouth.

"About a year from now."

"Hmm. He's living the dream up there." [Y/n] said, dreamily while putting her chin in the palm of her hand.

There is was again. The feeling of contentment when [Y/n] was with Senku. [Y/n] stared at Senku as he scooped some ice cream in his mouth and scrolling through his phone to show her something. "[Y/n]..." He said, making flinch a bit and looked away with a reddened face.

'What's going on with me today?' [Y/n] thought. 

The word love was stuck in [Y/n]'s head thanks to her mother. Senku showed [Y/n] his phone, bringing her back to reality. It was a picture of one of their projects. It was a robotic Senku. The last time they worked on it, it exploded in [Y/n]'s house.

"Oh, I almost forgot about Mecha-Senku." [Y/n] said.

"I think I found a way we can fix him." Senku said, and they began to happily talk about their projects. They talked and joked around like normal until they noticed the sun was setting. Senku took [Y/n] home.

"I'll see you tomorrow, Senku." [Y/n] said, but before [Y/n] could go inside, [Y/n] felt Senku place his hand on her head. She turned around and looked at him curiously. 

"Senku-" 

Senku interrupted her with a kiss. [Y/n]'s eyes widened a bit, and Senku pulled away. The hue of the sunset brought out [Y/n]'s shocked expression and her reddened face. Senku smiled, softly, stroked [Y/n]'s cheek with his thumb and walked away without saying another word. [Y/n]'s heart raced, and her legs felt like jello. She began to get extremely lightheaded. [Y/n] blinked a couple of times before walking into the house. 

To her surprise, her mother was home waiting for her.

"Welcome home. Were you out with Senku-kun again?" [Y/n]'s mother asked as [Y/n] closed the door. That's when her legs gave out. [Y/n] fell on her butt in front of the door, her eyes still wide with shock.

"[Y/n], are you alright?" Her mom joined her on the floor. It felt like a dream. Her world was spinning. [Y/n] placed her finger on her lips, where she could still feel the warmth of when her first kiss was stolen from her.

"Mother..." [Y/n] said with her widened eyes still focused on the tile flooring.

"Hmm?" she hummed.

"How...How do you know if you're in love?"

It took Ms. Sakurai a moment to process this. "WHAT??!!"

｡･:*:･ﾟ★｡･:*:･ﾟ☆

Of course, neither Senku nor [Y/n] ever mentioned the kiss ever again. But, Tsukasa was showing up around [Y/n] more frequently that Senku wasn't even in the picture much anymore. Now, they were in their third year of high school, and nothing between them has changed. Senku sat alone in the science lab, reflecting on his time with [Y/n] in this room. 

It was early December; graduation was coming up soon, too, meaning there wasn't much time for him to even consider confessing to [Y/n]. Thanks to Tsukasa, [Y/n] was changing. She smiled more, she had more friends, she stopped coming to Senku's house every day. She wasn't there when Senku's father came home.
