Gym Teacher! Error x Kind! Motherly! Female! reader

Error's POV
(You thought that I would start with you well nope). "Ok everybody I want all of you to do 15 laps around the gym without walking! GO START!" I yelled and blew my whistle. (That sounds very wrong btw). I hear everyone groan at this. I become annoyed. "C'mon guys be grateful that I took one lap away today now RUN!!!" I yell. Everyone starts running. I felt a bit weird though but I shrugged it off. The next class should come in soon. I feel weird again. I start to get a bit hot. 'I feel hot and a bit dizzy.' (He is not in heat alright). My son PJ comes up to me. "Dad you ok? Your face is a bit yellow. Do you to go to nurse Toriel?" He asked. "No I will be fine." I say a bit weak. I then almost fell. He caught me though. "I'll take you to her. Alright?" He asks clearly concerned about me. I nod. "Alright everyone listen up. I don't feel well today. But that doesn't mean you are off the hook. 15 laps now!" I yell. Everyone starts to run. PJ takes me to nurse Toriel. He says,"Miss Toriel my dad feels ill. Can you find out what is wrong?" He asks still concerned. She nods and sees whats wrong. PJ puts me on the bed. "It is just a fever. He will be fine but he can't come to school for a few days. Here take these. These pills will help. One dose everyday." Toriel says in her calm voice. "Thank you. Should I take him." He asks. "Yes it is the end of the day. (Through out the day he just felt hot but the end of the day he felt worse just so you know).

PJ and I leave the school and head home. He sets me on my bed and gives me the pills. I drink one and try to get some sleep. "Get well soon." He says with a smile and leaves the room. I drift off to sleep.

The next day

(Y/N) POV
I wake up, get dressed, eat, and drive to the school. I go to Miss Temmie's office. (Did I spell it right). "Morning Miss Temmie." I say with a smile on my face. "HoI MiSs (L/N). Oh wAit I nEED yOu to Do me a FaVOr." She said. "What is it." I say confused and a bit worried. "You will be the substitute teacher for gym since Mr Error has a fever." She says. "Alright. I will go to the gym now." U say determined to be a good teacher because I am just the principals assistant. I got to the gym.

I walked in and sat on the bleachers drinking coffee and waiting for the students to come in. 7 minutes pass and students came in the gym. They looked really confused. Later the bell rings signaling everyone should be in class. "Where is Mr. Error? Is he sick?" A lot of students asked. "Everyone calm down please. I will be your substitute until he gets better. Now lets start class with 5 laps around the gym. Ok?" Everyone looked confused. "Is something wrong?" I ask a bit concerned. Did I mess up already? "No it is just that he gives us more laps." A cat said. "Oh. But you guys will get tired and exhausted so only 5 laps. You can start." I blew the whistle. Everyone started running.

Once they were done I decide they should play a game or sport. "Ok since you are all done how about you all play basket ball. I'll set you guys in teams." I set them all in teams and they start playing. They all looked happy. "Ok. How about we take a break. You can get a drink of water and chat for 5 minutes. I don't want you guys dehydrated or tired." I said with a smile hoping I am a good teacher. "This is very weird." Said the same cat guy. "What do you mean? Doesn't your teacher do this all the time?" I asked. They all said no in unison. Then a fish lady said,"We mostly run around the gym until class is over. We only play games if he is in a good mood." Oh ok. "Well I won't do that anyways enjoy your break." I said cheerfully. They all smile. I heard one of them say,"You're the best!" I smile at that. After break we resume with basket ball. The bell rings. "Bye I will see you all tomorrow!" I yelled while waving good bye. They wave at me too.

Time skip to the end of the day

I was happy they all seem to like me. I work for a bit then leave the gym. I saw Mr. Dream look sad. I walk over to him. "Hey you ok?" I asked worried. "My brother looked sad for the past 4 days. I don't know what to do." He said in a sad tone. He looked like he wanted to cry. I hug him. I pull away and said,"I suggest you treat your brother like a king. Like cook his favorite food, buy stuff he is interested stuff like that. Then talk to him about it. I did That with my little sister." I say trying to make him feel better. He smiles and nods. He leaves and I leave too. I head to the store and buy 4 packs of big bags of candy. I head home and sit on the couch.
