The reader is whatever age you want them to be in this since school stress can happen at any age.

Tony:

You wanted your father to be proud of you, plus, everyone expects you to be as smart as your father, which is very stressful. So currently you sat behind your desk, trying not to cry as you shakingly wrote down words. When suddenly a knock came on the door causing you to flinch before telling the person to enter. It was Tony, holding a shirt. He just smiled as he held it out to you, saying he spot it so he bought it for you. It was a shirt with your favorite band on it. When tears suddenly poured down your face, Tony flinched before he nervously said "I knew you would like the shirt, but, euhm, isn't crying about it a bit too much?" So he just awkwardly stroked your back till you managed to yell out this homework is too hard. Tony just gave you a smile as he said he will help with it later, but now you deserve a break and your favorite snack.

Steve:

He was bothering you by asking million of asking about how his laptop works while you were already trying to study the subject you have a lot of trouble with. So eventually you just gave him a fake smile and asked if he can leave his son/daughter to study in peace. He blinked before he quickly nod and left. But five minutes later, he returned, having another question, only for you to throw your book aside him and shout for him to leave and ask Tony or some other technology nerd to help him out. After a few seconds of you panting, Steve slowly came out of hiding from behind the doorway before asking if something is wrong. So you automatically began crying, yelling everything is so hard. Steve just sat aside you as he held you, stroking your hair, whispering he will help. The next day, he had bought you a plushie you wanted as a reward for your hard work.

Clint:

He was acting like a bird again, your siblings were annoying you, wanting your attention. Your mom gave you some water, giving your shoulder a pat before she went to go tell your siblings to stop distracting you. But eventually it got too much so you just got up, stormed up the stairs before slamming your door shut. Clint was quick to shout not to slam the doors in this house. But he frowned, worried before he creeped up the stairs and peeked in your room to see you crying on your bed. He sighed before he sat down aside you, rubbing your back, asking if school is becoming too much so you nod. He stared before he grinned. He picked you up causing you to yelp before he kicked the school book to the other side of the room, saying he will tell the school you're sick so you can get a little vacation. He carried you down stairs before giving you your favorite snack. Your mother glared at him, but he didn't care, he was more focused on making his child happy.

Natasha:

She is a Romanoff, she immediately sensed it, as if it was her sixth sense, that something is wrong with you. She spied on you, trying to figure it out. When she realized it was school stress that was making you so depressed and distant, she got an idea. So while studying one day, she walked in, shut the books, threw them away from you before smiling and saying you two are going to your favorite place outside so you can relax and stop worrying about school. When you said you have homework, she just whispered with a wink that she will give you the answers if you go relax.

Bruce:

He was explaining the same time for the third time, but you still didn't get it, so nervously asked if he can explain it again. He just sighed and told you to focus before repeating what he said. But when you wrote down stuff, he said that's wrong, so you couldn't help but throw your pen and yell you don't understand anything. He was shocked for a second before he sighed and went to go pick up the pen, telling you not to throw with things before he laid it on your book, telling you if you don't study, you won't pass your exams. So you continued studying, but after a half hour, you had tears running down, sobbing out you can't do it. Bruce just gave you sad eyes as he stroked your hair, saying you can continue tomorrow and he will try to find a way to make this all easier. So the next day, he had found an easier way to explain it, a way that actually worked and helped you understand everything.

Thor:

Asgardian school is waaay harder than Earth school. There are difficult words, weird things about different realms and species. With so much difficult, weird info you have to remember, it kept slipping your mind. Thor kept repeating it all as if it was the easiest thing in the world, causing you to grow angry and yell for him to stop repeating it as if that will help. So you both got into an argument. You have a feeling the whole realm heard you two shouting at each other. So at the end, you ran away to the garden, where you hide and cried. Loki went and informed Thor where you are. Thor was quick to run to the spot you were hiding, apologizing for shouting at you instead of helping you. He wanted to give you a beer as reward, but Loki shouted you're too young.
