Mob Psycho 100 Oneshots and Scenarios ♡

Serizawa × Reader *Ibogami Hot Springs*

[A/N]: I wanted to make a Reigen fic for Reigen's Birthday, but I thought it would've been too late for that whenever I would get it done, so here! A Serizawa fic instead!! This is basically the last episode of season 2, I thought it was a cute filler episode so I thought it would be fun to write about it! This might be the longest chapter I've made so far, so enjoy! 💖💖💖

~~~  

It was quite a long time ago when you met Katsuya Serizawa, or as you like to call him, Kat-chan. You met when you were just a measly guard working under Toichiro, your boss. You became friends quickly when you first met Serizawa when he became a recruit from his life as a shut-in. After Mob defeated your now former boss, it opened up your personality, getting away from that suffocating job. You had an interview with Reigen along with Serizawa to keep him company and help out with his anxiety, thankfully, you both got the job!

You're currently packing a small bag of necessities, you were excited to take a trip to Ibogami Hot Springs, offered by Reigen, an offer which you graciously accepted. You hadn't had a vacation in over 5 years due to your past job as a guard. Heading out the door, you close and lock it, a quiet, excited squeal left you as you walked off (or- somewhat ran-).

The crowded streets you made your way through finally cleared to find Reigen on the corner sidewalk, he was alone. "Ah, hello Arataka, good to see you again!" He looks at you and you pause, coming to a stop, "Ah- was I a little too early..??" You sweat a bit. "Nothing wrong with that, in fact, you're quite punctual. Mob and his little brother should be here in a few minutes!" He smiled. "Good to hear!" you reply gleefully.

"Also.." You continue, "Thank you for accepting Serizawa's internship. He really needs it."

"It's nothing." Reigen wafted his hand.

"Well, I just have one request if it isn't too much trouble, he's trying his best a-and..." You fidget a bit, "Just.. Don't get too mad at him. He takes it personally when you claim he isn't doing a good job."

The topic ends at just the right time, as Mob and Ritsu showed up.

"Good morning master, good morning (Y/N)!" Mob smiled slightly, his brother and Dimple tagged along beside him. "Hello Mob!" You ruffle his hair. You look over to Ritsu, "Ah, you must be his brother, nice to meet you!" Ritsu smiled, "Nice to meet you too."

Reigen commented and Ritsu's smile fades, "That's quite a bit of gear you got Ritsu, I didn't think you'd come so prepared."

".. Yeah, thanks for inviting me I guess..."

Reigen faked a smile and mumbled a bit in an irritated matter.

Meanwhile, you begin to pace around a bit, getting impatient with Serizawa and his timing. "What if he slept in, or if he forgot something, or if he got anxiety and got sick, or-" You spoke quietly to yourself.

Reigen overheard then began to laugh, "You really worry for him don't you?"

You blush, "It's instinct by now, I've known him for years.." You look to him and wearily laugh, suddenly you hear a voice from another direction.

"WAH! I HOPE I'M NOT TOO LATE!!!" Serizawa exclaimed, you look at him. He ran with a suitcase traveling behind him. You gasp and run to hug him, "Kat-chan!!" Once your arms wrapped around him he immediately froze, responding to your affection is usually easy for him, but in his 'work mode' you assume he wasn't able to since it isn't exactly permitted within a job. His face turned a light shade of red, a wave of embarrassment washed over him as he looked down to you. "Uh, why do you have a suitcase??" Reigen interrupted.
