No ones pov

Sero whined again and latched himself onto denkis leg, watching as his cg talked on the phone. Denki glanced down at sero and patted his head "mhm! I'll just be gone for a little while....okay! Just a fair warning sero is gonna be fussy, he never likes it when I have to leave for a long time...okay see you soon!" And with that Denki hung up the phone, putting his hands on his hips and looking down at sero "baby I'm gonna need you to get off my leg" sero shook his head "nu!" Denki smiled softly "baby I promise I'll be back as soon as I can" sero shook his head again "no no no nooooo" he whined louder, flopping onto his back and crossing his arms. Denki sighed softly and knelt next to the boy, gently petting his hair "baby I'm sorry I have to go but you can't be acting like this" he gently picked sero up and placed him down on the bed.

Soon a knock at the door was heard, Denki looked over and opened it, smiling as Mina stood outside the door "hey!" He wrapped his arms around her, Mina smiled and hugged his back "what's up!" Denki shrugged "nothing much" he grabbed his bag, alerting sero and making him grabbed onto denkis leg again. Mina raised an eyebrow and giggled "hey little squirt" she ruffled his hair, making him pout "baby I gotta go" sero shook his head "no!" Sero whined and gave Denki his best set of puppy eyes. Denki leaned down and kissed his cheek "I'm sorry baby" he gently took sero off his leg, turning to Mina "if he gets out of hand just call me, I'll come back as soon as I can" and with that Denki walked out. Humming softly and making sure his phone was on vibrate, just incase.

Sero watched Denki leave as Mina shut the door behind him, he got up and laid on his bed. Frowning and turning away from Mina, who sighed and walked over. Sitting down at the edge of the bed, holding up a coloring book "hey buddy, I know you're upset, but maybe coloring will help?" Sero slowly turned his head over, looking at the dinosaur coloring book in her hand. He nodded his head and sat up, a pout still on his face as Mina handed him some crayons, gently popping his paci into his mouth. Sero picked up a pink crayon and began to color a t-Rex pink, Mina smiled softly as she watch him, his legs gently swinging back and forth. Softly suckling on his paci, he got done coloring a picture, holding it up for Mina to see. The pink haired girl looked over and smiles "Aww it's so pretty! I love the colors you used" Mina took a picture of it and sent it to Denki "your so talented baby"

Sero giggled and scooted off the bed, sitting down on the floor. Mina sat in front of him, noticing he was getting mentally smaller. She gently covered her face "where Mimi" she cooed, sero looked over and frowned, sloppily grabbing her wrists and pulling her hands away from her face, Mina gasped and smiled wide "there she is!" Sero giggled and let her squish his cheeks, Mina took out his building blocks. Gently placing them infront of him, sero got excited and began to build a bunch of small towers. Grabbing his large dinosaur plushie and knocking them down with it, laughing softly. Mina hummed happily as she watched this happen, happy that sero had calmed down. After a while though, sero became fussy again, throwing his paci at Mina. She frowned and tried to think of what she could do to make him feel better.

After a bit of thinking she got up and looked in denkis mini fridge, pulling out a premade sippy cup full of choccy milk. Handing it to sero, he immediately latched onto it, slowly drinking from it as he clutched his baby blankie in his hand. Mina checked the time, smiling softly as she cleaned up his blocks and race cars, taking him to the bathroom so that he could brush his teeth. While Mina waited for him to leave the bathroom, she turned on the fairy lights, turned on his train nightlight and made sure most of his stuffies were on the bed. Soon Denki texted, asking if he could FaceTime sero before he went to bed. Mina, of course, said yes, tucking sero into the blankies before handing him her phone to FaceTime Denki. He squeaked with joy and waved at the camera "hey baby!" Denki smiled wide, waving back at sero "hi dada!" Sero hugged his dinosaur stuffie to his chest.

Babbling to Denki about his day, how Mina gave him his sippy cup or how she played peek-a-boo with him. Denki listened to all of it, commenting on some parts of it, praising sero for being such a good boy while he was away. Promising he would buy him a treat if he went to bed all nice and thanked Mina for taking care of him. Sero nodded "otay!" He got super excited and bounce happily, Denki checked the time and smiled "okay bubba I gotta go now, get some sleep okay?" Sero quickly nodded his head, a small pout on his face as Denki blew him a kiss and hung up. Mina took back her phone and kissed Seros forehead as he laid back down. Picking up 'the giving tree' to read to sero. She sat at the edge of the bed, showing sero the pictures as she read, Seros paci bobbed in his mouth as she read, he tiredly rubbed his eyes and snuggled his stuffie.

Once the story ended Mina turned off the light, the fairy lights and nightlight lit up the room dimly, making sero not so scared to fall asleep. Mina stayed in the room with sero, watching as he closed his eyes and slowly drifted to sleep. Snoring softly, Mina stoof up and slowly left the room, staying nearby till Denki came back, smiling softly and waving to him as he headed to his dorm room to lay with sero. As Mina walked back to her dorm room, she could clearly hear the loud squeal of a very happy sero, who woke up to Denki cuddling him.
